Compute Compound Interest Monthy (int principal, float rate, int years) compute interest and return the amount based on initial investment (principal) and yearly rate and how many years. Compute compound interest monthly, so you have divide the rate by 12 to get the rate per month, then use it monthly for all the months in the how many years specified.

Use this version to compute the total (principal plus interest) after 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 years for an amount 10,000. Then print the total for the 10 years in row with proper heading for each column as following:

Principal Year_1 Year_2 Year_3 Year_4 Year_5 Year_6 Year_7 Year_8 Year_9 Year_10

Do the above for principal amounts 10,000, 15,000, and 20,000. The end printing result should be a table with the above headings and 3 rows for each principal.
