Answer 2

There's no way you can do without if-else but you can do it recursively which don't need loop.

If the number is limited to only 3 digits then you can hardcode it.

#include <iostream>
using namespace std;

int reverse(int num, int sum) {
if(num > 0)
return reverse(num/10, ((sum * 10) + ((num % 10) * 10)));
else
return sum;
}

int main() {
cout << reverse(3, 0) / 10 << endl;
return 0;
}
