Let us c Q.A positive integer is entered through the keyboard, write a function to find the binary equivalent of this number using recursion.

CH-5J(d).c

#include <stdio.h>

int fun(int num);
int main()
{
    int num;
    printf("Enter Number: ");
    scanf("%d", &num);

    printf("Decimal To Binary: %d", fun(num));
}

int fun(int num)
{
    if (num == 0)
    {
        return 0;
    }
    else
    {
        return ((num % 2) + 10 * fun(num / 2));
    }
}
