Our task is to develop a program that simulates Transactions within a bank. Please note the

client in this document is referred to the Bank. Users are persons who have an account with the

bank. The program has the following features:

$1.$ The User needs to first enter the correct pin. The user has $3$ tries to enter the correct pin.

The system will exit by itself after $3$ tries.

$2.$ After entering the correct pin, the user can perform withdrawals and deposits on an account.

$3.$ The client wants each user to only be able to perform up to $4$ transactions per successful pin

entry. After a max of $4$ transactions the user should be returned to the main menu where

they must enter their pin again or exit the program.

$4.($optional$)$ The user can exit the program without making all $4$ transactions.

The client has provided some test data shown below that can be used as the initial dollar

amounts within the accounts
