Implementation/Coding Requirements

• Must provide program description/history comment.
• Declare and initialize descriptive local variables at the beginning of the main function.
• Variable names must follow Google naming convention.
• Must use the right data type for different kinds of data. For example must use int for number of years, not double or must use double or float for loan amount, not int.
• All variables except property annual tax rate must be declared locally inside the main function.
• Output must be aligned and formatted nicely as shown above.
• In the main function the program flow must be properly structured as shown below:
  • variable declarations
  • obtain user input such as property zip code, address, property offer price, down payment percentage, annual interest rate and number of years financing using cin statements. You may assume users will enter correct data for your program. No need to perform data validation.
  • pause the program using the provided pause function (see NOTE at the end).
  • perform loan calculations.
  • output the results.

Note: Generally it's considered a bad programming practice and low maintainability to obtain one single data then do some computation then obtain another single data then do some computation. It will be much easier for debugging and maintainability purposes to obtain all data then perform all calculations together as indicated in the main function program's flow above. Failure to do this will result in heavy point deduction.

Mortgage payment calculations

• You can assume the property's annual tax rate is fixed at 1.5 %. Use a global constant double variable to represent this value.
• Loan amount = principal x (1 – down payment /100)
• Monthly interest rate = annual interest rate / 1200
• Mortgage monthly payment = loan amount x monthly interest rate / ( 1 - 1 / Math.pow (1+ monthly interest rate, number of years * 12) )
• Property tax monthly payment = principal x property tax rate / 100 / 12
• Monthly payment (property tax included) = mortgage payment + property tax payment
• Total payment = mortgage monthly payment x 12  x  number of years
• Loan maturity date: 12/31/ (2019 + number of years financing)
