C Comments


C comments are used to give a brief description about any specific line of code or about a module in the code to make the code more user-friendly.

C Comments can be of two types:

  • Single line Comments
  • Multi line Comments

Single Line Comments:

Single line comments can be used for commenting a line of the code or to write a single line description about the code. The lines starting with // is considered as single line comment.

Multi Line Comments:

Multi line comments can be used for commenting a part of the code or to write a multiple lines description about the code. The lines enclosed between /* */ are considered as multi line comments.

Example:

#include <stdio.h>
 
int main()
{
// Performing Arithmetic Operations without using brackets.    
	int sum1 = 10+20*10-90*10+700;  
 
/* Performing Arithmetic Operations
using brackets to clarify the expression.*/
 
	int sum2 = (10+20)*10-(90*10)+700;
	printf ("%d", sum1);
	printf ("\n");
	printf ("%d", sum2);
 
	return 0;
}

Output

100
