Introduction

Control flow statements form the basis of all programming tasks. You will find yourself using if statements, for$-$loops and while$-$loops throughout your

programming career. This week we will use our if statements and loops to build a simple future value calculator that will tell the user their expected

account balance and interest earned each year.

Expectations

Your program should do the following tasks:

Ask user for their initial investment, expected interest rate, and the number of years they plan to invest

Print an error message if any of these inputs are negative or non$-$numerical values

Print the annual interest and balance to the screen for each year from $1$ to $N,$ where $N$ is the number of years the investor plans to invest

Print the ending balance and a message indicating this will be the final balance

Ask the user if they want to continue $($i$.$e$.$ re$-$run the program using new inputs$)$

$($Optional$-$Extra Credit$)$ Add functionality to the calculator that allows the user to add a fixed additional principal amount to their account each year
