Write a recursive solution to print reverse of a number.

reverse.c

#include <stdio.h>
#include <math.h>

int reverse(int );
int main()
{
    int num;
    printf("Enter a num: ");
    scanf(" %i",&num);
    printf("The reverse of given integer is: %i \n",reverse(num));
    return 0;
}
int reverse(int x)
{
    if(x==0)
        return 0;
    int dig=log10(x);
    return (x%10)*pow(10,dig) + reverse(x/10);
}
