Reversing the digits

[Tanushreeagr]

//PROGRAM TO REVERSE THE 5 DIGIT NUMBER
#include <stdio.h>
void main()
{

int num, i = 0;

char rev[5];

printf("Enter any 5 digit number\n");

scanf("%d", &num);
i = 0;
while(num)
{


rev[i] = num % 10;// IS THIS RIGHT WAY TO ASSIGN CHARACTER ARRAY?????

i++;

num = num/10;
}

printf("%s", rev);

}

What's wrong in the above program.

WHILE DISPLAYING i am not getting correct output. whats wrong in rev[] array.

PLEASE HELP!!!
