Practice Problem 4: Bank Charges

Objective: To calculate bank charges and verify input using if-statements

Please do Programming Challenge #6 at the end of Chapter 4 (page 212). Here's my brief summary of the book's description:

• A bank charges $10 per month plus:
  • $0.10 for each check if you write less than 20 checks
  • $0.08 for each check if you write between 20-39 checks
  • $0.06 for each check if you write between 40-59 checks
  • $0.04 for each check if you write 60 or more checks
• The bank also charges $15 if the balance falls below $400 (before any fees are applied - a slight change/clarification from the book's description)
• If the user enters a negative number of checks, output an error message and don't calculate any check fees. If a negative value is given for the beginning balance, display an urgent message indicating the account is overdrawn, but still calculate fees.
• The book doesn't say what to do if fees make it overdrawn. What do you think should be done? Personally, I think a message indicating so would be a good idea. But this is not required.

Compilation and Sample Input/Output on Unix:

bash-2.04$ aCC -AA lab2.cpp
bash-2.04$ a.out
Enter the following information about your checking account.
Beginning balance: $1000
Number of checks written: 50

The bank fee this month is $13.00

bash-2.04$ a.out
Enter the following information about your checking account.
Beginning balance: $405.25
Number of checks written: 5

The bank fee this month is $10.50

bash-2.04$ a.out
Enter the following information about your checking account.
Beginning balance: $100.05
Number of checks written: 100

The bank fee this month is $29.00

bash-2.04$ a.out
Enter the following information about your checking account.
Beginning balance: $-5
Number of checks written: -10

Your account is overdrawn!
Number of checks must be zero or more.
bash-2.04$

Rules

• Save both the source code and the output it produced after you compiled and ran it. You should save these in a plain text file with a file extension of either .txt or .cpp.
  
• Put comments at the top of your program with your name, the name of your C++ source file, the name of this assignment and class (CS 110A Practice Problem 4), and a brief description of what the program does. Format it so that it is readable and professional.
  
• Follow the standard conventions for indentation, meaningful variable names, etc. like the textbook.
  
• The output should show the above test cases.
