Exercise:

Give change

Objetive:

Create a Visual Basic (VB.net) program to give change for a purchase, using the largest possible coins (or bills). Suppose we have an unlimited amount of coins (or bills) of 100, 50, 20, 10, 5, 2, and 1, and there are no decimals. Therefore, the execution could be something like this:

Price? 44
Paid? 100
Your change is 56: 50 5 1
Price? 1
Paid? 100
Your change is 99: 50 20 20 5 2 2

Code:

Imports System
Public Class Exercise47
    Public Shared Sub Main()
        Dim price, paid, change As Integer
        Console.Write("Price? ")
        price = Convert.ToInt32(Console.ReadLine())
        Console.Write("Paid? ")
        paid = Convert.ToInt32(Console.ReadLine())
        change = paid - price
        Console.Write("Your change is {0}: ", change)

While change > 0

If change >= 50 Then
                Console.Write("50 ")
                change -= 50
            Else

If change >= 20 Then
                    Console.Write("20 ")
                    change -= 20
                Else

If change >= 10 Then
                        Console.Write("10 ")
                        change -= 10
                    Else

                            Console.Write("5 ")
                            change -= 5
                        Else

If change >= 2 Then
                                Console.Write("2 ")
                                change -= 2
