Reversing a string without using array or pointer.

This program will reverse a string without using array or pointer (only a character variable)

Before looking at the program try to solve it by yourself.

Hint : Use recursion 

#include<stdio.h>

char ch()

{

    char c;

    c=getchar();

    if(c==EOF)return 'a';

    ch();

    printf("%c",c);

}

void main()

{

    ch();

}

Happy Coding. :)
