Question

You are writing a new program. What information should be contained in a comment block at the top of that program? Pretend that you are explaining this concept to a new student that has never programmed before.

Answer 1

In the comment block the aim of the program should be stated.what is the purpose of the program should be mentioned clearly.

Example:

// the aim of the program is to add two numers And place the result in the third number

#include<stdio.h>

int main()

{

int a, b, c;

printf("Enter two numbers to add\n");

scanf("%d%d", &a, &b);

c = a + b;

printf("Sum of the numbers = %d\n", c);

return 0;

}

For this instance it is a small problem .there were large program having 1000 ' s of lines of code .for those program comments are very useful to understand the logic going on in the code
