Comments are merely program documentation which helps the reader to understand the code.
The compiler ignores these comments when it translates the program into executable code.
C language uses two different formats of comment
1. Block comment
2. Line comment
1. Block comment: A block comment is used when the comment will span several lines.
Example:
/*This is a block comment
that covers two lines*/ |
2. Line comment: The line comment uses two slashes (//).Programmers generally use this format for short comments.
Example:
//This is a single line comment |
Example program:
1 2 3 4 5 6 7 8 9 | /*This is a Greeting program, which prints ‘Hello world’. This program demonstrates some of the components of a simple c program*/ #include “stdio.h” #include “conio.h” void main() { printf(“Hello World”); //This statement prints Hello World getch(); }//main() |
