CPP program to calculate the power

 In this solution try to solve, the problem of finding the power of a number manually and with pow() function in the cpp programming language.

Firstly, look at manually finding the power of any number.

Code:

#include <iostream>

using namespace std;

int main() 

{

    int exponent;

    float base, pow = 1;

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

    cin >> base >> exponent;

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

    for(int i=1;i<=exponent;i++){

        pow *= base;

    }

    cout << pow;

    

    return 0;

}

Output:

Enter base and exponent respectively:  3

3

3^3 = 27

Compute the power of the number by using pow() function from the cmath library.

code:

#include <iostream>

#include<cmath>

using namespace std;

int main() 

{

    int exponent;

    float base, powe = 1;

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

    cin >> base >> exponent;

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

   powe=pow(base, exponent);

    cout << powe;

    

    return 0;

}

Output:

Enter base and exponent respectively:  3

3

3^3 = 27
