Assignment Description:
In this assignment you will create a program that allows a user to choose one of the following main menu items:
C) Create new user account (Create an account with userId/password) L) Login
V) View promotions
Q) Quit the program
If User enters an option other than (uppercase or lowercase) C, L, V, or Q, the program does not do anything and shows a message wrong option and displays the menu again.
When user enters option C, the program asks the user to enter a userId and a password and successfully returns back to the main menu. The login and password should be stored in a file.
If the user chooses option L, the program will display the login prompt and then, it will ask for the password. At this stage, the entered login and password are compared to the stored login/password pair and proper message will show up if the match was not found which takes the user back to the main menu.
If the user chooses option V, the program will display the message: Thank you for using our bank and Future Computer Programmer ATM Machine! For your continued support, we are offering 3% cash back on all debit purchases.
Now, if login was successful, the following banking menu will be display to let the user choose one of the following tasks:
W) Withdraw money. D) Deposit money.
B) Request balance. Q) Quit the program.
(again, remember that if the user enters an option other than (uppercase or lowercase) W, D, B, Q, the program should show a message and display the menu again.)
The initial balance for the user account should be $0.00
If the user chooses option W, the program should ask the user to enter amount user wishes to withdraw.
Validation: In the case of withdraw, if the amount is more than balance the user should be notified and no withdraw will occur.
If the user chooses option D, the program should ask the user how much amount the user wishes to deposit and add it to initial balance.
If the user chooses option B, the program should display the balance amount in the user account.

Additional Instructions:
All transactions should be stored in a file called transHistory.output as shown above for the Review Account Activities History.
NOTE: Do Not Use Excessive Global Variables. Using Global Variables in most functions may result in losing points for the designated function.
Choose the parameters and return types that you feel are right for the appropriate methods. Again, do not use an excessive amount of Global Variables, as you will lose points.
Please make sure your code has following functions:
1. char mainMenu(); //main menu, first thing the user sees. Displays the menu and gets the value for selection
2. void createAccount(); //will only display if the user has selected to create an account. Allows the user to enter his/her ID and password and then stores this login information in a file called accounts.txt
3. void login(); //this function gets the user name and password from the user. Must then match this account info, by comparing it to every item in the file accounts.txt, to indicate whether or not login was successful
4. char bankingMenu(): //will only display if the user has selected to log in.
5. void deposit (); //allows the user to put money into their accounts, prints success or fail upon deposit 6. void withdraw(); //allows the user to get money from their accounts, prints success or fail upon deposit
7. void displayBalance(); //shows the balance on the screen
8. void ShowTransHist(); //get the transaction history from the file path string and display
You can use additional functions (optional) for input validation and withdrawal amount validation. Your program should make use appropriate switch and if-else statements where necessary.
