Write a program in c++ that calls a function that returns the smallest of three floating-point numbers

Write a c++ program that contains a “main” and 4 functions: In the main function declare 4 integer variables x, y, z and m and call the following functions: The first function is to initialize the 4 variables using the last 4 digits of your university ID number. For example, if your ID number is 43956789 then you x=6, y=7, z=8, and m =9. The second function should calculate and print the average of the 4 variables. The third function is to find the largest number of the 3 variables. The last function should double the values of the 4 variables. For example if x = 6 then x will become 12.

Question: In C#, how can I recreate this into a Windows form Application instead of a console application? Please show a photo of the display and show the code that you used, thank you!   Problem: Write a function Seperate( number ) that separates an integer number (ranging from 0 to 99999) into its digits. For example, if the number is 42329, the function finds 4, 2, 3, 2, 9. If the number is 323, the function finds 0, 0, 3, 2, 3. (Hint: use modulus and integer division operations.) Code: using System;public class RecExercise4{static void Main(){Console.Write("Input any number (ranging from 0 to 99999) : ");int num = Convert.ToInt32(Console.ReadLine());Console.Write(" The digits in the number are : ");separateDigits(num);} static void separateDigits(int n){int i = 4;int[] arr;arr = new int[5];while (i>-1){arr[i] = n%10;n = n/10;i--;}foreach(int j in arr)Console.Write(" " + j);}}

In Haskell: Code a function "rangeProduct" that takes two arguments. The function should return 0 if the second argument is smaller than the first, otherwise it should return the product of the range between two numbers, ex: rangeProduct 3 5 --> 60 (because 3*4*5 = 60) What to do for negative numbers to do (if anything) is up to you. Write the program without recursion first and then write it with recursion.
