Question

THE PROBLEM: The nice folks from the Lion Lending Company have hired you to write some software that will process their daily loan information. The data will come from a text file that has the following format:

The first line will contain an integer: number of loan applications

There will be two rows for each of the customers

First line will be the customer's (1) first name and (2) last name, separated by a space (assume there is no spaces in the actual names)

Second line will contain: (1) number of years (an integer), (2) amount of the loan (floating-point number), (3) annual interest rate stated as a percent value (floating-point number), (4) the amount per month that the customer is qualified (floating-point number)

A sample data file looks like this:

3

Mickey Mouse

20 100000 4.75 1000

Donald Duck

30 200000 5.25 1000

Minnie Mouse

30 245000 4.75 1500

The program should begin by asking the user for the name of the input file. If the file does not exist, a message should be displayed and the program should end.

For each customer, the program should compute the monthly mortgage payment using the following formula:

P = (r(PV)) / (1 - (1 + r)^-n)

P= Payment

PV = Present Value

r = rate per period

n = number of periods

Notes: The Present Value is the loan amount the customer has requested. The rate per period is the annual rate divided by the number of periods per year (which 12 since payments are made monthly). If the rate given was 3.0%, for example, the rate per period would be (3.0/100)/12, or .0025. The number of periods is the total number of payments made over the course of the loan. A 20-year loan would have 20*12, or 240 payments.

The program should display a table with the loan information. For each user, you should display first name, last name, the qualified amount, and the monthly payment. If the monthly payment is not more than the qualified amount, the program should also display the number of payments, the total amount paid, the loan amount, and the total interest paid.

The formatting for the table is important. Column headings should be displayed above each column. Names should align to the left and the numbers aligned to the right. Two decimals should be output for floating-point numbers. The output that would correspond to the input file from the previous page is displayed below.

After the table, your program should output the total number of loan applications, the number of qualified loans, and the average loan payment of the qualified loans.

First     Last      Qualified    Payment Number Total Paid    Loan Amount   Total Interest

Mickey    Mouse      1000.00      646.22   240     155092.80     100000.00      55092.80

Donald    Duck       1000.00     1104.41

Minnie    Mouse      1500.00     1278.04   360     460094.40     245000.00     215094.40

Number of loan applications: 3

Number of qualified loans:   2

Average loan payment: 962.13
