/*P4Q5
 *Name:Wang Chaoran
 *Description:
 * (Comparing loans with various interest rates) Write a program that lets the user enter the loan amount
 * and loan period in number of years and displays the monthly and total payments for each interest rate
 * starting from 5% to 8%, with an increment of 1/8. Suppose you enter the loan amount 10,000 for five years;
 * display a table as follows:
Loan Amount: 10000
Number of Years: 5
Interest Rate     Monthly Payment     Total Payment

5%                188.71              11322.74
5.125%            189.28              11357.13
5.25%             189.85              11391.59

...
7.85%             202.16              12129.97
8.0%              202.76              12165.83
