1. 15. 1. Adding Comments

Comments in a C program have a starting point and an ending point.

Everything between those two points is ignored by the compiler.


  /* This is how a comment looks in the C language */
  

The beginning of the comment is marked by the slash and the asterisk: /*.

The end of the comment is marked by the asterisk and the slash: */.

  
#include <stdio.h>
 
int main(){
   /* This is the comment.*/
   printf("%15s","right\n");
   printf("%-15s","left\n");
   return(0);
}

        
               right
      left
