1. Our Modern ATM machine has the following Menu
a. Create new account
i. When user selects this option, ask for username and password. Create a new text file with his/her name. If user already exists then ask the user to enter another name.
b. Cash Withdraw
i. Ask the user the amount he/she wants to withdraw. Check his account if the user has that amount of money in his/her account. If the amount exceeds, a message should be display saying that please enter less amount.
c. Cash Deposit
d. Fill Cash in ATM
i. Ask for amount and add in ATM machine.
f. The menu should be displayed again after every action. E.g., After cash withdrawal ATM software should display the menu again instead of exiting.
