Suppose you want to deposit a certain amount of money into a savings account and leave it alone to draw inferest for the next 10 years. At the end of 10 years, you would like to have $10,000 in the account. How much do you need to deposit today to make that happen? You can use the following formula to find out: P=(1+t)nR - P is the present value, or the amount that you need to deposit today. - F is the future value that you want in the account. - r is the annual interest rate. - n is the number of years that you plan to let the money sit in the account. The program should ask the user to enter the annual interest rate named r (say 5% ), then display the present value or amount (P) that need to deposited today. Other variables are given, so you can assign values as it mentioned
