/*
|
||||
This application manages transactions at a store check-out line. The
|
||||
check-out line has a cash register, and the register has a cash till
|
||||
that is prepared with a number of bills each morning. The till includes
|
||||
bills of four denominations: $1, $5, $10, and $20. The till is used
|
||||
to provide the customer with change during the transaction. The item
|
||||
cost is a randomly generated number between 2 and 49. The customer
|
||||
offers payment based on an algorithm that determines a number of bills
|
||||
in each denomination.
|
||||
|
||||
Each day, the cash till is loaded at the start of the day. As transactions
|
||||
occur, the cash till is managed in a method named MakeChange (customer
|
||||
payments go in and the change returned to the customer comes out). A
|
||||
separate "safety check" calculation that's used to verify the amount of
|
||||
money in the till is performed in the "main program". This safety check
|
||||
is used to ensure that logic in the MakeChange method is working as
|
||||
expected.

/*
|
||||
This application manages transactions at a store check-out line. The
|
||||
check-out line has a cash register, and the register has a cash till
|
||||
that is prepared with a number of bills each morning. The till includes
|
||||
bills of four denominations: $1, $5, $10, and $20. The till is used
|
||||
to provide the customer with change during the transaction. The item
|
||||
cost is a randomly generated number between 2 and 49. The customer
|
||||
offers payment based on an algorithm that determines a number of bills
|
||||
in each denomination.
|
||||
|
||||
Each day, the cash till is loaded at the start of the day. As transactions
|
||||
occur, the cash till is managed in a method named MakeChange (customer
|
||||
payments go in and the change returned to the customer comes out). A
|
||||
separate "safety check" calculation that's used to verify the amount of
|
||||
money in the till is performed in the "main program". This safety check
|
||||
is used to ensure that logic in the MakeChange method is working as
|
||||
expected.
