Abstract

The McBride Financial Services Company, a part of the Virtual Organizations, needs a computer program to calculate mortgage payments in their agent field offices. The agents want to input a mortgage loan amount, an interest rate, and a number to pay off the loan into this program and have the mortgage’s monthly payments as output. In addition, agents want the program to calculate the pay-off amount of the loan for a specific year(s) or an amortization table for the mortgage.

The benefits of this program are faster and more reliable than using manual calculations or an electronic calculator where they can still key in the wrong number. The program can also be ported to a company website. This website can be accessed by customers to inquire about mortgage information and thus free the agents’ time for such requests.

The program development cycle is the best approach for coding a program solution. The first paragraph has done the analyzing of the problem, then comes the design phase. The requirements for this task are identified as input, output, and processing tasks. Tasks are coded into a program module. This breaking down of tasks into modules is known as modular programming. According to Torres (2012),”Breaking down a programming project into modules makes it more manageable. These individual modules are easier to design, implement, and test. Then they can be used to construct the overall program.

Modular programming is an important and beneficial approach to programming problems. They make
