Sample Solution:

C# Sharp Code:

using System;

public class RecExercise15
{
    public static void Main()
    {
        // Declaring variables for base number, exponent, and result
        int bNum, pwr, result;

        // Prompting the user for the base value
        Console.Write("\n\n Recursion : Calculate power of any number :\n");
        Console.Write("------------------------------------------------\n");
        Console.Write(" Input the base value : ");
        bNum = Convert.ToInt32(Console.ReadLine());

        // Prompting the user for the exponent
        Console.Write(" Input the exponent : ");
        pwr = Convert.ToInt32(Console.ReadLine());

        // Calling the function to calculate the power
        result = CalcuOfPower(bNum, pwr);

        // Displaying the result
        Console.Write(" The value of {0} to the power of {1} is : {2} \n\n", bNum, pwr, result);
    }

    // Recursive function to calculate power
    public static int CalcuOfPower(int x, int y)
    {
        // Base case: when the exponent is 0, return 1
        if (y == 0)
            return 1;
        else
            // Recursive case: multiply base number x by itself (y - 1) times
            return x * CalcuOfPower(x, y - 1);
    }
}

Sample Output:

 Recursion : Calculate power of any number :                                                                  
------------------------------------------------                                                              
 Input the base  value : 2                                                                                    
 Input the exponent : 6                                                                                       
 The value of 2 to the power of 6 is : 64
