Extra Credit Challenge Exercise (due by 11:59 pm): The amount, A, which will be in a bank account that earns compound interest, is calculated with the following formula: nt A=P(1 + n) where P is the principle (the amount originally deposited in the account), r is the annual interest rate (as a decimal, i.e. 3%.03), n is the number of times the interest is compounded (how often interest earnings are paid into the account), and t is the number of year the account earns interest. Write a script which prompts the user for a principle amount, interest rate, and how often the interest is compounded. The script should calculate the amount that will be in the account after 1, 5, 15, and 30 years. Use fprintf to display this information to the user. The amount in the account should be rounded to the nearest cent when displayed to the user
