Find the Power of a Number in C++

In this article I would like to share with you a sample program that will ask the user to give a base and exponent and then our program will compute the power of the number using C++.

I am currently accepting programming work, it project, school

    cin >> expo;

    /* Calculates base^expo */
    power = pow(base, expo);
    
    cout << setprecision(2) << fixed;
    cout << "\n\n";
    cout <<"\tTHE RESULT";
    cout <<"\n\n";
    cout << "\t"<<base << " ^ " <<expo <<" = " << power;
    cout << "\n\n";
    return 0;
