#include <stdio.h>                         //header file

int main()                              //main function

    length=strlen(name);             //stores length os string
    p=name+length;     
 // assigning total address as in given string; it becomes total taken from variable length starting from //0.
    //p=name takes address location 0 to pointer.
    while(p>=name)                 //the value of 'p' decreases from total location  until it reaches 0.

        p--;                             //decreases the value
