1 Class Test 10 Question 1 Create a console application using visual studio 2012 ultimate. Figure 1 Use recursion to create a menu, DO NOT use a while, do while or for loop. When any value is entered that is not part of the menu choices, the menu must be shown again. After each menu option is finished executing the menu must be shown again, except for the exit option which closes the program. You may use global variables for this program. See figure 1. Menu option A: Call a method that makes use of a do while loop to prompt the user to enter a valid number. This number will be the amount of values that will be entered. See figure 2. Figure 2 Menu option B: Call a method that uses a for loop to prompt the user to enter a value(string or int) for the amount of times specified by menu option A. Determine if the value entered is a number or text and store it in the appropriate variable. See figure 3. Figure 3 Menu Option C: Display the numbers, text, amount of numbers and the amount of text. See figure 4. Figure 4

2 Question 2 Consider the following scenario: A boy, Peter had his birthday and got R500. He wants to buy toys for himself with his birthday money. He decides to spend almost all of it in one shopping trip on toys, but does not know beforehand what toys he wants. Peter refuses to leave the shop without at least buying one toy and when Peter decides on a toy to buy, he buys it and it can t be returned. Peter wants to know after he bought a toy if he can afford the next toy he is interested in and he wants to stop buying toys when he has less than R50 left. Draw a flowchart to assist Peter in his toy shopping. Question 3 Consider the flowchart in figure 5. This is a flowchart of a simple game. Create a console application that matches the flow chart. Figure 5 MEMO namespace Question1 class Program static int inumber, inumbercount, itextcount; static string snumbers, stext; static void Main(string[] args) inumber = inumbercount = itextcount = 0; snumbers = stext = ""; Menu(); private static void Menu() Console.Clear(); Console.WriteLine("(A)Enter number of values to enter");
