Proposed exercise

Create a function named "Power" to calculate the result of raising an integer number to another (positive integer) number. It must return another integer number. For example. Power(2,3) should return 8.

Note: You MUST use a repetitive structure, such as "for " or "while", you cannot use Math.Pow.



using System;
public class F_Power
public static void Main()
Console.Write("Base: ");
int number = Convert.ToInt32( Console.ReadLine() );

Console.Write("Exponent: ");
int exponent = Convert.ToInt32( Console.ReadLine() );

Console.WriteLine("{0} ^ {1} = {2}",number, 
exponent, Power(number, exponent));

public static int Power(int number, int exponent)
int result = 1;

for(int i = 0; i < exponent; i++)
result *= number;

return result;
