Power (C++)

Power

calculatePower() calculates the power of an integer positive value and it takes 2 parameter:

no takes the value whose power is to be determined.

power is the exponent value.

Both arguments to this function should be positive integers.

Code

#include "stdafx.h"

#include "iostream"

#include "conio.h"

using namespace std;

int calculatePower(int no, int power)

{

    int ans = no;

          

    if (power == 0)

              return 1;

    else if (power == 1)

              return ans;

    else

    {

       for (int i = 1; i < power; i++)

            ans = ans * no;

              return ans;

    }  

}

int main()

{

       cout<<calculatePower( 2 , 0 );cout<<endl;

       cout<<calculatePower( 2 , 1 );cout<<endl;

       cout<<calculatePower( 2 , 2 );cout<<endl;

       cout<<calculatePower( 2 , 3 );cout<<endl;

       cout<<calculatePower( 2 , 4 );cout<<endl;

       cout<<calculatePower( 2 , 5 );cout<<endl;

       cout<<calculatePower( 2 , 6 );cout<<endl;

       cout<<calculatePower( 2 , 7 );cout<<endl;

       cout<<calculatePower( 2 , 8 );cout<<endl;

       cout<<calculatePower( 2 , 9 );cout<<endl;

       _getche();

       return 0;

}
