C++ Program to Calculate Power Using Recursion

To understand this example, you should have the knowledge of the following C++ programming topics:

Example: Program to Computer Power Using Recursion

#include <iostream>
using namespace std;

int calculatePower(int, int);

int main()
    int base, powerRaised, result;

    cout << "Enter base number: ";
    cin >> base;

    cout << "Enter power number(positive integer): ";
    cin >> powerRaised;

    result = calculatePower(base, powerRaised);
    cout << base << "^" << powerRaised << " = " << result;

    return 0;

int calculatePower(int base, int powerRaised)
    if (powerRaised != 0)
        return (base*calculatePower(base, powerRaised-1));
        return 1;


Enter base number: 3
Enter power number(positive integer): 4
3^4 = 81

This technique can only calculate power if the exponent is a positive integer.

To find power of any number, you can use the pow() function.

result = pow(base, exponent);
