Read through Chapter 6 in your textbook before starting this assignment. Start with your checkbook balancing program from assignment 2 that helps you balance a checkbook at the end of a monthly statement period. Modify your program as follows: • The user should enter the transaction type and amount (if required) on a single line. If there is a problem with the command (invalid transaction type or invalid amount), print an error message and have the user re-enter the whole comma You should never have a separate prompt for just the transaction type or for just the transaction amount. Note that this means that you do not need validation loops. The validation is done using selection (if or switch) inside the main transaction processing loop. You just need the one transaction processing loop that reads a command on each iteration. • You must divide your program into at least three different functions: a main function, a check-processing function and a deposit-processing function. You can add other functions if you want to. • Add additional service charges as described below. • Allow the program to start with an initial balance that is positive, zero or negative. There are no restrictions on the starting balance. This means is that the user could start a month with a negative balance. These changes may require substantial reorganization of your program. Program Input The program commands (user input) are as follows (see the sample program dialog near the bottom of this page). Transaction command Meaning Process a check for amount dollars, where amount is a floating-point number. Process a deposit for amount dollars, where amount is a floating-point number. Perform end-of-month processing and end the program. С атоunt D amount E Service Charges • There is a $0.35 service charge for each check written. • If the account balance falls below $1000.00 at any time during the month, there is a $10.00 service charge (low balance charge) for the month. If the balance stays at $1000 or more during the entire monthly statement period (program execution), there is no low balance charge for the month. Otherwise, there is a single $10.00 low balance charge for the month. • If processing a check results in a negative balance, there is a $30.00 service charge (insufficient funds charge). This $30.00 fee is charged for each check that results in a negative balance. • Note: Do not any deduct service charges from the account balance until the end of the month.
