Write a C++ program to implement a recursive function to calculate the power of a number.

#include <iostream>
using namespace std;

int pow(int x, int b)
{
    if (b == 1 )
    {
        return x;
    }
    else if(x == 0 && b == 0)
    {
        return 0;
    }
    else if(b == 0)
    {
        return 1;
    }
    else
    {
        return x * pow(x, b - 1);
    }
}

int main() {

    int x;
    int b;
    cin >> x; cin >> b;
    cout << pow(x,b);

}
