Instructions You are working as a computer programmer for a mortgage company that provides loans to consumers for residential housing. Your task is to create an application to be used by the loan officers of the company when presenting loan options to its customers. The application will be a mortgage calculator that determines a monthly payment for loans and produces an amortization schedule for the life of the loan. The company offers 10-, 15-, and 30-year fixed loans. Inputs The program should initially prompt the user (the loan officer) for the principal of the loan (i.e. the amount that is being borrowed). It should then ask him or her to enter an annual interest rate for the loan. The final input should be the number of years that the loan will be outstanding. Because the company only offers three different terms (10-, 15-, and 30-year loans), the program should ensure that no other terms are entered. Payment Calculator The formula to calculate the monthly payment for a fixed…
