An Introduction to Programming through C++ : Command line arguments and reading inputs from a file in Codeblocks
Dear Students,
One of the questions asked during the live session is how to read input from a file instead of typing in Codeblocks. For example, suppose our program name is sum.cpp and it takes two arguments and prints the sum. Then, in the command line we use to type: sum.cpp < input.txt where the inputs are stored inside input.txt. Well, we can achieve the same inside Codeblocks as follows.
Before going into the details of reading inputs from file, let us first learn how to read command line arguments in Codeblocks, and then we will see how to read from input file with < operator.
A) Steps for reading command line arguments:
- Create a project in Codeblocks by clicking on: File -> New - > Project
- It will prompt you to choose a project type, then choose consolde application (if you are unaware of any project type)
- It will ask you for a name and a location to create the project.
- Finally, a project will be created in a folder you have chosen. Inside the project folder, under the source, you will find main.cpp by default.
- You need to modify this main.cpp according to your need.
- Next, how to set the command line arguments in Codeblocks. Go to: Project -> Set Program's Arguments you can fill the arguments you like to have in command line, each argument should be separated by a space.
- Then, you can compile/build and run the project, where the main.cpp will be executed.
- Create a file which contains the inputs, say input.txt remember its full path.
- Now, follow the same as given under A, i.e., use Project -> Set Program's Arguments to achieve it.
- However, instead of typing the arguments in the dialog textbox, you need to write the input file name with full path name. For example: </home/dillip/input.txt should be written in the dialog textbox for argument. Note that < operator acts as re-direction exactly like it does in command promt or terminal. Then, the program reads from the given file name, in this case, input.txt which is stored under /home/dillip/ directory.
- Then, execute your project by compile/build, you will find that your program is taking inputs from the file.
You may try more options and explore more possibilities. For instance, you may also read from a file using Tool and adding a tool to do it.
Hopefully, it helps.

an Introduction to Programming through C++ : Explanation for Q9 of Assignment 12
Dear Students,
As many of you face issues in understanding the concept of map and its elements, the solution of Q9 of Assignment is explained below.
Note that this question contains mainly two types of data structure from Standard Template Library (STL), namely, vector and map. Hence, let us have a quick understanding of these data structures briefly before explaining the actual answer. We will use T on behalf of the (primitive) data types like int, float, double, etc., for generalization. Also, below we will describe some idioms which will be used later as arguments.
1. Vector<T> P; declaring (defining) such variable means we are generating an array which length can be expanded or shrinked internally to adjust the size. Then, one of the ways to access the elements of P is through indices just like an array, e.g., P[0] refers to the first element, P[1] refers to the second element, and so on.
2. map< <T>, <T> > P; declaring a map variable P where the first T refers to the type of key and second one refers to the type of value. Mention that in a map, an element has two attributes, namely, key and value; commonly known as (key,value) pair. Now, one of the ways to access the element is to write P[key] which will maps the given key to a value. Here, key can be any type, if we assume that key is int then P[10] refers to an element in map variable P where the key is 10. Similary, if key is of string type then we can write P["India"] which means that the key is "India" and it maps to its corresponding value.
3. Note the difference in vector and map for accessing the element. For example, let us assume that both vector and string deal with int data type only. Then, for a vector P[10] means the element at 11th position, whereas for a map P[10] means the element having the key as 10.
Based on the above idioms, let us analyze each of the options given in Q9.
Option (a) map<int, map<string, int> > P; which has key of int type and value of map type in the first level map. Again, in the second level the map, the key is string type and value as int type. Now, when we derefence P[10]["abc"][20] then 10 refers to the key for first level map, "abc" refers to the key of second level map. However, 20 does not fit into key or value type since it is written as if a key but there are no more level of map or other data types like vector, it suppose to be a value if we write P[10]["abc"] = 20 which is not the case. Hence, this option is discarded.
Option (b) Array of map<string, map<int,double> > which can be written as map<string, map<int,double> > P[100]; where 100 is the size of the array of maps. Note that here we have three levels, first level is an array, second level is a map having string type as key and value as map type which is the third level, again, in the third level the map has key as int type and value as double type. Now, let us deference P[10]["abc"][20] and see whether it is valid or not. At first level, 10 is the index of array of maps, then at the second level "abc" is the key of map type. Next, at the third level 20 is the key of inner map which is of int type. Here all dereferencing fits the declariont. Moreover, one particular assignment could be P[10]["abc"][20] = 5.5; which is correct. Thus, this option is correct.
Option (c) vector<map<string,map<int,double> > > P; declaration says that P is a vector of maps (first level) where each map has string as key and map as value (second level), and lastly, each of the inner map has int type as key and double type as values. So, it has got three levels and now let us dereference P[10]["abc"][20]. At the first level, 10 is the index of 11th element; at the second level "abc" is the key of map (outer), and at the third level 20 is the key of map (inner). Again, all the dereferencing is successful here and we can have a particular assignment like P[10]["abc"][20] = 5.5. Thus, this option is also correct in terms of refering the variable as P[10]["abc"][20].
Option (d) vector<map<string,vector<string> > > P; it infers that P is a vector of maps (first level) where each map (second level) has a key of string type and value as vector type (third level), so, it has three levels. Now, let us match our types by dereferencing the variable P[10]["abc"][20]. Now, 10 refers to the index of vector at the first level, "abc" refers to the key of map at second level, and lastly, the trickiest one, 20 refers to the index of vector which is of string type. Here, the number of levels of derefencing and the respective types are matching. Further, we can have an assignment statement like P[10]["abc"][20] = "Delhi"; which is correct, Hence, this option of refering the variable of this type is correct.
Please read the declaration and traversal of elements of maps, vectors, sets, etc. Hopefully, you will understand the above arguments.
withsing you happy Diwali,
NPTEL Team.

An Introduction to Programming through C++ : Clarification on Q2 of Assignment 10
Dear Learners,
This is an explaination for memory leak which was asked in Q2 of Assignment 10.
Memory leak may occur when the memory is allocated dynamically, i.e., using new keyword in C++. Memory leak will happen when the dynamically allocated memory is no longer used or necessary but it is not de-allocated explicitly (using delete keyword in C++). Note that the memory allocated using new keyword stays linked to the program even if the associated variable goes out of scope in some way. Furthermore, memory leak also occurs when the pointer of reference to the dynamically allocated memory is overwritten without saving the address to another variable, i.e., the address of the dynamically allocated memory is lost due to lack of backup. Then, we will not be able to use the dynamically allocated memory since the pointer is either pointing to some other address or goes out of scope. In any of the cases, the memory leak lasts until the end of the execution of the program, the operating system recollects such memory leaks including other allocated memory to a program after the end of the program.
In this view, for Q2, both the answers option b and d are correct, which are - (b) The program has a memory leak (d) The program does not do anything interesting, but it does not have any specific errors either. The marks will be adjusted accordingly in the process of re-evaluation.

About the cosmological simulation program
Note that for the purposes of calculation the stars in our program can be in 3 dimensional space, i.e. each position, velocity, acceleration has x, y, z coordinate. For the purpose of visualization, we are only using the x, y coordinates.
Furthermore, in our input data, we have all z coordinates set to 0, and the z components of the velocities are also 0. Thus, the stars will always remain confined to z=0 plane. Thus the visualization will be exact. However, if the stars were moving in 3 space, then our visualization will not be correct -- what you would see is a projection on the positions on the x,y plane. There are other ways of visualizing 3 space, e.g. by something called "perspective projection". But this is outside the scope of the course.

An Introduction to Programming through C++ - Notes for Lambda Expression and Range-Based Statement
Dear Learners,
We have seen lamda expressions and range-based statement in lecture videos. Particularly, lambda expressions are used for defining unnamed or anonymous functions (for details see https://docs.microsoft.com/en-us/cpp/cpp/lambda-expressions-in-cpp?view=vs-2019). Range-based statement is used in loops, mainly for loops, to iterate over the elements of data types or data structure including user-defined ones (for details see https://docs.microsoft.com/en-us/cpp/cpp/range-based-for-statement-cpp?view=vs-2019).
Note that lambda expression and/or range-based statement are the features of C++11. Hence, these may not be compatible with old compilers. Certainly GCC should be fresh enough (>=4.7) to support all these modern C++ 11 standards. The older compilers may not support this format and it needs to pass -std=c++11 flag to compile your program, say program.cpp. Specifically, to use such for loop in your code, apply one of the following instructions according to your settings.
1.CASE-1: without installing simplecpp in command line:
- use g++ -std=c++0x program.cpp or g++ -std=c++11 program.cpp to compile
- If these commands do not work then do the following steps and then repeat the above commands.
- i. Know your compiler version,run: which g++ or g++ --version
- ii. To switch to g++ 4.7 (assuming that you have installed it in your machine),run: sudo update-alternatives --config gcc() command line : g++ -std=c++0x program.cpp or g++ -std=c++11 program.cpp
- use s++ program.cpp to compile your file.
- Settings -> Compiler -> Tab "Compiler Flags" -> Option "Have g++ follow the C++11 ISO C++ [-std=c++11]" (check this option)

An Introduction to Programming through C++ - Clarifications on Week 8 Assignment
Dear Students,
This is to clarify some of the doubts and issues regarding assignments of week-8 which are elaborated as follows.
Thank you all for your inputs in the discussion forum.
with best regards,
NPTEL Team
Some practice problems for week 8 (not to be submitted)
We scrapped problems 10-12 because of some typos. However, these problems are interesting and I am writing down the correct description here for you to practice.
-------
A two dimensional array is useful for storing image. If we have a black and white image with m rows each having n pixels, this is easily represented using a bool array A[m][n], where true indicates black colour and false indicates white. The following code counts the number of vertical lines in a picture. A vertical line is a
contiguous sequence of black pixels, one below the other, of any positive length, terminated on either end by a white pixel or by the end of the picture.
int found=0;
for(int i=0; i<m; i++)
for(int j=0; j<n; j++)
//beginning of inner iteration
if(A[i][j]){
found++;
for(int k=i; k<m; k++){
if(A[k][j]) A[k][j] = false;
else break;
}
}
cout << found << endl;
Suppose that originally the image A contained 3 vertical lines.
Consider the point in time when control reaches the beginning of the
inner iteration, and i=25, j=16, and found = 2.
1. Which of the following is true?
(a) A[10][40] must be false.
(b) A[10][40] must be true.
(c) A[10][40] may be true or false, we do not know which based on what is given.
2. Which of the following is true?
(a) A[25][40] must be false.
(b) A[25][40] must be true.
(c) A[25][40] may be true or false, we do not know which based on what is given.
3. How many vertical lines will be present in the image at this point?
An Introduction to Programming through C++ - Assignment 8: Q10 to Q12 are dropped
Dear Students,
Kindly note that Q10 to Q12 of Assignment 8 are not going to be considered for grading.
Actually, there is a mistake in the question itself, i.e., the code which leads to several confusions. Hence, please do not attempt Q10 to Q12 of Assignment 8, those questions will be discarded while evaluating the assignment and will not affect the grading.
Sorry for the inconvience, kindly cooperate and ignore Q10 to Q12 of Assignment 8 while submitting the assignment.

NPTEL Team
Quiz for week 8: clarification for problems 10-12
The context to this question is from a very early lecture where we talked about how to represent images. This is chapter 2 of the book, and week 1 second lecture. There we had said that images can be represented in a long sequence (which is similar to a 1 dimensional array). But as you will observe, an image is much better stored in a two dimensional array: value of pixel in row i column j is stored in element [i][j]. The code is supposed to be checking whether the picture contains a single vertical line -- though the code does a bit more. How to check for a vertical line was discussed in chapter 2 also, here you need to adapt the check to the context of 2 dimensional arrays. Furthermore, in this code we want to really know whether there is anything besides the line (or several lines, which is what the code checks for). So the code is erasing vertical lines as soon as it finds them, i.e. making the pixel white. If you want more clarification, I suggest you try running the code. You can try it on your own computer or on some online compiler (since we do not need simplecpp features any longer) such ashttps://www.onlinegdb.com/online_c++_compiler -- there are others too, just do a search.
Quiz for week 8: small correction
The code before 1) contains the line "cout buff". Please ignore this line.
Programming Assignment 7-3
I will discuss this in some detail. Let us consider the input given in the assignment
2
This means there are 2 days. On the first day 10 letters arrive. These go into the pile, and the order of letters, bottom to top is
1 2 3 4 5 6 7 8 9 10
Of these, the bureaucrat processes the top 8 on the first day. So at the end of the day, the pile, from bottom to top has the following letters.
1 2
The next day, 9 letters arrive, these are labelled 11, 2, 3, 4, 5, 6, 7, 8. 9. These go on top of the pile. So the pile now has the following letters, bottom to top.
1 2 11 2 3 4 5 6 7 8 9
On the second day, the bureaucrat processes 8 letters, again those at the top. So what remains is:
1 2 11
Which is what you were expected to print, one number per line.
The key to solving this problem is to understand how to use an array to store the letters in the pile. You need to figure out at what index to place the letter at the bottom of the pile, where to place the letter that arrives next, and so on. The general ideas should be similar to taxi dispatch, in which we also had to keep the index of where the next driver will be placed etc.

An Introduction to Programming through C++ - Assignment 7 Re-evaluated
Dear Students,
Based on the discussions, it was found that Q4. option (d) is also correct and hence it is included in the answer set. In addition, for Q12, a couple of students have answered as A[n-1] instead of A[0]. Note that if there is only one element in the array (n==1) you do not have to write an expression n-1 to get a zero, rather you should write a simplified anaswer (i.e., A[0] ) which is clearly mentioned in the question. This time it is awarded marks but please do not continue such practice which will not be graded in forthcoming assignments.
Kindly, check your marks for Q4 and Q12.
thanks and regards,

An Introduction to Programming through C++ - Clarification on Q7 Assignment 7
Dear Students,
Q7 has a minor mistake in the question description especially in the second loop, thanks to Mr. Vipul who pointed it out. Hence, the modified question is as follows.
Suppose I am given arrays x[0..9], y[0..9] such that x[i], y[i] are x,y coordinates of the ith point. I wish to decide if any 3 of these are on the same straight line using the following code fragment:
bool collinear = false;
for(int i=9; i>=0; i--)
for(int j=j1; j>=0; j--)
for(int k=k1; k>=0; k--){
if(collinear3(x,y,i,j,k))
collinear = true; // function collinear3 returns true if ith, jth, kth points are collinear
}
Some clarifications and hints for quiz for week 6
Hint for problem 1: If I just had red blocks and blue blocks, then the situation would have been exactly like poetic meters. The number of different towers using these blocks would be the same as the number of poetic meters using short and long syllables. In fact you could take a poetic meter, change s to a red block and L to a blue block, and you would get a tower. The problem given is a generalization -- but you can approach it exactly the way Virahanka did.
Clarification for problems 8-9: It appears that codeblocks is not allowing lambda expressions. I will look into this. I hope the quiz questions are simple enough that you can answer without this. Alternatively, you can use the online C++ compilers such as
These will not have graphics, or repeat, or the keyword main_program, but everything else, including lambda expressions will work fine. There are other online compilers also.
Clarification for problem 10: Please write exactly what the program prints. In this case the program will not print commas but will print spaces, so use spaces.

An Introduction to Programming through C++ - Assignment 5 - format for Question 2,3,4
Dear Learners,
Here is the format for answering Q2,3,4 of Assignment 5.
Apply comma between multiple elements without any spaces, please read the instructions given above. For these questions, a character input is required in the function call. Hence, input it as you pass a character constant. For example, we have two variables for the function call of this question, one is character and other one is an integer. Consequently, there are two blanks for a function call. Let us say the character is 'x' and the number is 100 then, you should write your answer as follows.
'x',100
Now, if you have to answer for four blanks then write in the following format.
'x',100,'y',200
If you have not answered in the same way as discussed above, then change your answer to the format above and resubmit.
Good luck

An Introduction to Programming through C++ - Week 4 Programming Assignments Not to be Graded
Dear Learners,
This is to inform you that Programming Assignment for Week-4 (4-1,4-2,4-3) are decided to be ungraded. These questions are basically about writing codes for common mathematical functions, which results in approximate answers. However, at present there is not sufficient facility to verify the answers of these questions since a set of answers are acceptable. Therefore, the weights of these programming assignment are set 0 and it will not affect your grades irrespective of submission.
However, students can pursue these assignment as good means for practice and try to write the codes. In fact, some of the students have already submitted these assignments, which is definitely useful for understanding the programming mechanism. Hence, rest of the students are highly encouraged to attempt to code these programs. Note that there may be a programming test for the final certificate examination.
Coding is essential to test your programming skills and to implement your ideas. Learn these techniques and gain confidence through these programming assignments.
best of luck,

An Introduction to Programming through C++ - Submission of Programming Assignments
Dear Students,
It was noted that a few of the students encountered run-time error while submitting the programming assignments. According to our team, the main cause of such run-time error is that the last minute submission of assignment.
Kindly note that programming assignments have certain weightage in the final grading. Hence, if you really concerned about the marks then please follow the following conventions regarding programming assignment submission.
- Always submit your programming assignment well ahead of the deadline, avoid rush in the last minute.
- Compile and run your program in Swayam interface.
- Verify correctness of the answers for public test cases. Proceed only if all of those are correct.
- You need to submit your programming assignments apart from writing the code and compilation. Some of the students are forgetting to submit the assignment.
- Always report issues if any well in advance in the forum, preferably in the specific thread created by NPTEL team, or at least write an appropriate subject (heading) in your query to distinguish it from Quiz.
Good luck,

Quiz 2 Problem 11
This is the problem in which you were given a plan, and you were to give code which fits the plan.
The solution is d. You will see that if we assume that the values are as given in the plan at the beginning of iteration t, and if we execute the code of option d, then the values in iteration t+1 will indeed be as given in the plan.
It is true that option b will also produce the final answer. However, this does not do what was asked: give code which follows the plan. If you assume that at beginning of iteration t the value of i was t-1 and the value of term was 1/t!, then the first step of option b would cause term to become 1/t!/t which is not 1/(t+1)! as needed at the beginning of iteration t+1.
So option b is incorrect.

An Introduction to Programming through C++ - Prerequisites for re-evaluation of Assignment
Dear Students,
Last week, we have recorded a numerous requests for re-evaluation of various questions and programming assignment. Please remember that re-evaluation needs sufficient evidence. Here are some of the notes which are absolutely mandatory to incur re-evaluation.
- Take screenshots only in desktop.
- Justify your answer with valid arguments and proofs if necessary.
- Take suitable assumptions which are trivial and not affecting the answer.
- For Quiz answers where multiple elements are present in a single answer, kindly segregate those with comma or space or as instructed in the question.
- For Programming Assignment, it is necessary to submit the assignment apart from compile and run. Always take screenshots which show that (1) your code has passed compilation and (2) you have submitted the program. So, there will be at least two screenshots for Programming Assignments.
- If a dedicated announcement is given in the discussion forum regarding re-evaluation then please place your queries only to that thread with your answers as specified in that announcement.

Lastly, remember that a programming statement is an single entity, so, you need to write it as a statement with or without spaces as applicable (e.g.- int x; or x=x+1;). However, if there are multiple statements to answered in a single text-box then use comma in between those statements (e.g.- punUp();,forward(90);,penDown();,forward(-90);).

Issues with evaluation and display of Assignment 1 scores
Dear Students,
NPTEL Team
An Introduction to Programming through C++ : Due date for Assignment 2 Extended!
Based on requests received, we are extending the deadline of the assignment 2.
Deadline for Assignment 2 has been extended till August 21, 2019 - 23:59 IST
Deadline for Programming Assignments 2-1 and 2-2 has been extended till August 22, 2019 - 23:59 IST
Assignment 1 will close on 14 August 2019 - 23:59 IST, as per the original deadline.
Clarification about problems 12-14 of Quiz: Assignment 2
1. Please assume that the input given to the program, n, will always
be > 0. Further, assume that n is the total number of terms to be
added, including the first term. In other words the program computes
the sum 1 + 1/1! + 1/2! + ... 1/(n-1)! This is slightly different from
what the program in the lecture did.
2. In question 13, you are asked to give the number of divisions needed
for n=10. So this the number of divisions needed to calculate 1 + 1/1!
+ ... 1/9!.
3. In question 14, you are asked to give the number of divisions needed
for n=10 by the program from the lecture. So this the number of
divisions needed to calculate 1 + 1/1! + ... 1/10!

If your programming assignment works on your computer but not when submitted on-lline
Sometimes the difference might be very minor, e.g. you are printing an endl while the answer does not contain that endl. Or you may be printing a prompt "Please enter n:" while in general we dont expect you to print any prompt.
If you carefully see the "actual output" and the "expected output", you should be able to spot the difference. That should tell you what you can do to change your code so that it produces what we expect.
We realize that we may be forcing you to change your program even though in some sense your program was already correct. Please note that a computer is grading your program, and so your output must exactly match what we have given as the answer. Please bear with this; it should be easy to make the minor change because the expected and actual outputs are being shown.
Mistake corrected in Assignment 1-2
There was a mistake which has now been corrected. Please submit the solution now.
Regarding codeblocks problems
Many students have installed codeblocks from the codeblocks site. This will not work.
You need to install codeblocks from www.cse.iitb.ac.in/~ranade/simplecpp -- pick the correct (novice) version for windows or linux as you need. These versions have simplecpp already configured inside them.
For windows: If you installed another codeblocks earlier, then you need to uninstall it first. It appears that the uninstallation does not work nicely, and so you might in addition need to rename the folder C:\mingw to something else, say c:\oldmingw.
Sorry this is a bit complicated.
Programming assignment and demo to show submission
Three programming assignments have been released. Two of them are for you to submit, the third is a demo. To submit, you have to first select the language. You can select only C++. Once you do that, a textbox will appear in which you have to type in the program. In the program, you dont need to type in "#include <simplecpp>", this is already there. You just have to type in the main program as usual. After you finish typing, press the compile and run button. This will compile the program and show if there are textual mistakes in your program. You should correct these and then again press compile and run. If the compilation is successful, your program will be run. The input values to the program are already stored by us in "test cases". These values will be used. What your program produces and what is expected will also be shown.
The "Demo Assignment" is not for you to do, but is given so that you can see an example of how the process works. When you open it you will see the statement and the test cases and the expected output and actual output for the test cases we have already stored. If you again press on "select language" and choose C++, you will also see the code as you would be expected to type in the text box. Do not worry about the messages "due date exceeded"; as said above this only to show you the process.

Regarding using simplecpp for graphics
We realize that several people have had difficulty in installing simplecpp. We will work with everyone to see that this gets done. But this might take some time.
However, even now you will be able to do some programming -- specifically you will be able to solve the programming assignments that we will give without having installed simplecpp. This is because the programming assignments have to be done on-line, and the on-line system has simplecpp to the extent required for the assignment.
So in summary, we will help you install simplecpp. However, you should do the programming assignments that we will release soon even if you are unable to install simplecpp.
