We can use Single line and Multiple Line Comments in C language. Comments are used to make our program more informative and expressive, also used in cases where we want some lines of code to be skipped from execution.
Single Line Comment
#include<stdio.h>
void main()
{
printf("Single line comment");
//comments in c language
}

Multiple Line Comment
#include<stdio.h>
void main()
{
printf("Multiple line comment");

}
