OUTPUT
All values input and used in the calculations as well as the monthly payment and total
monthly house cost need to be output as follows:
MONTHLY COST OF HOUSE
SELLING PRICE
$XXXXXX.XX
DOWN PΑΥΜENT
XXXXXX.XХ
AMOUNT OF LOAN
XXXXXX.XX
INTEREST RATE
XX.X%
ΤAX RΑΤΕ
XX.X%
DURATION OF LOAN (YEARS)

MORTGAGE
XXXX.ХX
UTILITIES
XXXX.XX
PROPERTY TAXES
XXXX.XX
INSURANCE
ХXXX.XX
$ XXXXX.XX

Write a C++ program to calculate the monthly cost of a house given the selling price,
annual rate of interest, and number of years for the loan. The monthly mortgage payment
may be computed using the following formula:
payment =
a*i(1+i)ª
(1 + i)ª – 1 where a=amount of loan
i=rate of interest per compounding period
(annual rate/12)
n=number of compounding periods (yrs*12)
Assume that the down payment will be 20% of selling price, yearly tax rate is 1.25% of
selling price, utilities will be approximately $300.00 per month, and insurance will be
$550.00 per year.
DATA
Use preprocessor statements to set the tax rate, cost of insurance, and the cost of utilities.
Set the percentage of down payment as a non-global memory constant. Prompt the user
for the selling price, the rate of interest, and the number of years for the loan.
CALCULATIONS
Use at least four functions in addition to main: a function to input all data, a function
which handles all computations including invoking a subfunction to compute the down
payment, amount of loan, and mortgage payment, and, finally, one to output the results.
