Instructions
Write a C program that will allow a user to interact with a simulated bank account. The account will start with a 0 balance every time the program starts and the program is only responsible for dealing with the account's balance, don't worry about interest rates or anything other than the balance.
The Menu
Your application should display the following menu for the user and continue to show them the menu after each of their choices are complete until the user chooses option 4 to quit. The user should be informed if they make an invalid choice and the menu should be redisplayed.
1. Show Balance
2. Deposit
3. Withdraw
4. Exit
Menu Description
1. The show balance option should allow the user to view the nicely formatted balance of their account.
2. and 3. The deposit and withdraw options should allow the user to deposit money in, or withdraw money from their account. To do this the user will need to be prompted for an amount. The amount the user enters needs to be a positive number for both deposit and withdraw and needs to be less than the balance for withdraw. After either option is successful the user should be able to see that their balance has changed by choosing option 1 from the menu.
4. Quit the application
The program should provide enough output/feedback to the user to be friendly and easy to use.
