C++ Program to Find Power of Number using Recursion

C++ Program to calculate exponential of a number using recursion

C++ Program to calculate exponential of a number using recursion

#include <iostream>
 
using namespace std;
 
int getPower(int base, int exponent);
 
int main(){
    int base, exponent, counter, result = 1;
    cout << "Enter base and exponent\n";
    cin >> base >> exponent;
      
    result = getPower(base, exponent);
      
    cout << base << "^" << exponent << " = " << result;
    return 0;
}
/*
 * Function to calculate base^exponent using recursion
 */
int getPower(int base, int exponent){
    /* Recursion termination condition,
     * Anything^0 = 1
     */
    if(exponent == 0){
        return 1;
    }
    return base * getPower(base, exponent - 1);
}

Output

Enter base and exponent

3^4 = 81
