Comments in C

Comments are used to comment on the line of code in the program. Comments are a way of inserting remarks and reminders into code without affecting its behavior. The compiler ignores comments, treating them as though they were whitespace. There are two types of comments:

  1. Single Line Comments
  2. Multiple Line Comments
Single Line Comments: Single line comment is used to comment on the single line of program code. The double slash (\\) is used to comment on a single line. Syntax:
/-----------------comment with double slash ---------------- /
Example
#include <stdio.h>
int main(){
// This comment line section will not be show at the time of output
printf("tutorialandexample.com");
return 0;
}
Output
tutorialandexample.com
Multiple Line Comment Multiple line comments are used to comment multiple line code of the program. The given syntax is used to comment multiple lines.  Syntax:
/* 
Code 1
code  2
code  3
*/
Example
#include <stdio.h>
int main(){
/*printing
Information
With Multiple Lines
*/
printf("Hello C");
return 0;
}
Output
Hello C
