Question

Write a function called integerPower(base, exponent) that returns the value of base^exponent

For example,

integerPower(3,4) = 3*3*3*3

• Assume that exponent is a non-zero integer, and base is an integer.
• Function integerPower should use for loop to control the calculation.

• Do NOT use any math library function.
• Inputs for this program, which are base and exponent, have to be entered by the user

An example of input/output dialog is shown below:

Enter Integer Base: 5
Enter Integer Exponent: 3
5 raised to the power of 3 = 125

Enter 0 if you'd like to end this program.
Enter 1 if you'd like to run this program again: 1

Enter Integer Base: 2
Enter Integer Exponent: 4
2 raised to the power of 4 = 16

Enter 0 if you'd like to end this program.
Enter 1 if you'd like to run this program again: 0

Have a nice day!

Answer 1

#include<iostream>

using namespace std;

int integerPower(int base, int exponent)

{

    int ans = 1;

    int i;

   

    for( i = 1 ; i <= exponent ; i++ )

        ans *= base;

       

    return ans;

}

int main()

{

    while(1)

    {

        cout<<"Enter Integer Base: ";

        int base;

       

        cin>>base;

       

        cout<<"Enter Integer Exponent: ";

        int exponent;

       

        cin>>exponent;

       

        cout<<base<<" raised to the power of "<<exponent<<" = "<<integerPower(base, exponent)<<endl;

       

        cout<<"\nEnter 0 if you'd like to end this program.";

        cout<<"\nEnter 1 if you'd like to run this program again: ";

       

        int choice;

       

        cin>>choice;

       

        // if user wants to quit

        if( choice != 1 )

            break;

           

        cout<<endl;

    }

}
