Write a C++ Program to Calculate Power of a Number

PROGRAM: C++ Program to Calculate Power of a Number

/* C++ Program to Calculate Power of a Number*/

 1: Compute Power Manually

#include <iostream>
using namespace std;

int main() 
{
    int exponent;
    float base, result = 1;

    cout << "Enter base and exponent respectively:  ";
    cin >> base >> exponent;

    cout << base << "^" << exponent << " = ";

    while (exponent != 0) {
        result *= base;
        --exponent;
    }

    cout << result;
    
    return 0;
}

2: Compute power using pow() Function

#include <iostream>
#include <cmath>

using namespace std;

int main() 
{
    float base, exponent, result;

    cout << "Enter base and exponent respectively:  ";
    cin >> base >> exponent;

    result = pow(base, exponent);

    cout << base << "^" << exponent << " = " << result;
    
    return 0;
}
