Question

Problem (1): write a c# program that reads an integer n, generate cube of the integer n read by calling the cube function. Continue the computation while n! = 0.

EX:

• Enter a value 5 Cube of 5 is 125

• Enter a value Cube of 2 is 8

• Enter a value 0 Cube of 0 is 0

Problem (2): Write a C# program to read 5 real numbers (Use an array of size 5 to store elements) and then print them in order and reverse order. Define functions ReadDepositArray, ShowDepositArrayInorder, and ShowDepositArrayReverse to perform this task.

Problem (3): The power function can be made faster by having it calculate x^n in a different way. We first notice that if n is a power of 2, then x^n can be computed by squaring. For example, x^4 is a square of x^2, so x^4 can be computed using only two multiplication instead of three. As it happens, this technique can be used even when n is not a power of 2. If n is even, we use the formula x^n = (x^n/2) ^2. If n is odd, then x^n = x times x^n-1. Write a recursive function that computes x^n.(The recursion ends when n=0, in which case the function returns 1.) To test your function, write a C# program that asks the user to enter values for x and n, calls power to compute x^n, and then displays the value returned by the function.

using System;

namespace cube
{
    class Program
    {
        public static void Main(string[] args)
        {
            int n=-1;
            while(n!=0){
            Console.WriteLine("Enter an integer: ");
            n=Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Cube of "+n +" is "+(n*n*n));
            }
            
            Console.ReadKey(true);
        }
    }
}
