[pow] Calculating Exponent Result (Iterative and Recursive)

#include <iostream>
using namespace std;

int recursivePower(int a, int n) {
    return n ? a * recursivePower(a, n - 1) : 1 ; //If n = 0, returns 1; otherwise calls itself with one less power
}

int iterativePower(int a, int n) {
    int result = 1;
    for (int i = 0; i < n; i++) //multiplies 'a' n times. thus, a * a * a = a^3
        result *= a;
    return result;
}

int main() {
    int A, N;

    cout << "Enter an Integer: ";
    cin >> A;
    cout << "Enter the exponent: ";
    cin >> N;

    cout << "Recursive Power: " << recursivePower(A, N) << endl;
    cout << "Iterative Power: " << iterativePower(A, N) << endl;

    return 0;
