Could you help me to understand how to write this code? For this quest, you are going to start with the Account and Transaction structs from the previous quest and write four functions:

addTransaction will ask for information for a transaction, check for valid date input, and create the newly created Transaction. Try to use uniform initialization for the return instead of creating a temporary variable.

newAccount takes in the last ID used for an account, increments it and asks for all the information for a new Account, except for the ID$.$ The past in and incremented ID is used for that. Again, try to use uniform initialization for the return value.

getCurrentBalance calculates and returns the current balance of a passed in instance of the Account struct. This will need to be calculated based on the beginning balance and transactions on the account.

findAccount uses linear search to find the account by its ID and return the index in the vector for that account. return $-1$ if not found

For the main function of this quest you will need to create a vector of Account structs and then should present a menu of options for the user.

"Add account" which calls the newAccount function and adds the new account to the vector of accounts

"Add Transaction"

asks for an account ID$,$

calls findAccount to get the index of the account

calls addTransaction to create a new transaction and pushes it onto the correct Account's transactions vector.

"Get Balance"

asks for an account ID$,$

calls findAccount to get the index of the account

calls getCurrentBlance, passing in the correct account

displays the account's balance on the terminal.

$$List Transactions$$

asks for an account ID

calls findAccount to get the index of the account

displays all transactions neatly on the screen.

HINT:: You may want to create a printTransaction function to help with this!

"Exit Program" This entire menu should be in a while loop that ends when this option is chosen.
