Comments in C

In C programming, comments are used to describe the functionality of code, making it easier for programmers to understand the code. Comments are ignored by the compiler and do not affect the execution of the program.

C supports two types of comments:

1. Single-line Comments:


2. Multi-line Comments:

1) Single Line Comments

Single line comments are represented by double slash . Let's see an example of a single line comment in C.

                
#include <stdio.h>
int main()
{    
    //printing information    
    printf("Hello C");    
return 0;  
}      
                
            

2) Multi-line Comments

Multi-Line comments are represented by slash asterisk * ... *. It can occupy many lines of code, but it can't be nested. Syntax:

                
#include <stdio.h>
int main()
{    
    /*printing information   
      Multi-Line Comment*/  
    printf("Hello C");    
    return 0;  
}
