PROGRAMMING ASSIGNMENT 6 INSTRUCTIONS
You have been tasked to write an application which will help your organization calculate the
monetary donations and expenses. Write a Visual Basic program to implement the cash
register in the diagram below. The program should have a class called CashRegister that keeps
track of the balance and adds and subtracts. The class should not permit a negative balance
since your organization would be fined heavily if you spend more than you take in. If the user
tries to subtract a number that would result in a negative balance, the system should produce a
messagebox indicating that the transaction would result in a negative balance, which is not
permitted.
