declaring a method

taks kamps

im trying to write a method called Power that takes two non-negative integer parameters and returns a value that is the first parameter raised to the power of the second (e.g. parameters 2, 3 will return 8, which is 2 x 2 x 2).

using System;

namespace HelloWorld
{
class Program
{

static void Main(string[] args)
{
int a = 2;
int b = 3;
int result = Power(a, b);
Console.WriteLine(result);
}
}
}

You can write program for power using loop as shown below in C#.Net
int a = 2;
            int b = 3;
            double  pnum = 1;

            if (b > 0)
            {
                for (int i = b; i>0; i--)
                    pnum = pnum * a;
            }
            else if(b <0)
            {
                for(int i=b; i<0; i++)
                    pnum = pnum/a;
            }

   Console.WriteLine("{0} Raised to the Power of {1} is {2}", a, b, pnum);
The output in console is as shown below-
2 Raised to the Power of 3 is 8

You can directly use Math.Pow() function as shown below
double result = Math.Pow(2, 3);
