Rules of Writing Comments

Before Writing Comment in C  we needs to know about some rules that used to write comments:-

Rules :-1 . Program Contain Any number of comments at any place:-

void main(/*Main Function*/)

{

int age; // Variable

printf("Enter Your Age : ");

scanf("%d",/*Type Age*/&age);

printf("Age is %d : ",/*Your age here*/age);

getch()

}

2 . Nested Comments are not allowed. [Comment within Comment are not allowed]

/* This is /*Print Hello */ 

printf("Hello");

3 . Comments can be split over more than one line.

printf("Hello");    /* This  
                       is 
                       Comment */

4 . Comments are not Case-Sensitive.

printf("Hello");
    /* This is Comment */
    /* THIS IS COMMENT */

5 . Single line Comments Starts with ‘//’

printf("Hello");

    // This is Single Line Comment
