Question

answer in c++ code.
use comments when writing the code to know what's your thinking.
there is three pictures with information

Write a C++ console program that defines and utilizes a class named ATM. This program will demonstrate a composition relationship among classes because an ATM can contain many Accounts. You will need to reuse/modify the Account class you created in Assignment 10. The default constructor for the ATM class should initialize a private vector of 10 accounts, each with an initial balance of $50. This will allow the user to interact with a few accounts for testing purposes. The ATM class should have a public method named logln(int) that receives the account ID. Valid IDs for the ATM correspond to valid indices for the vector. Once a valid ID is entered, call a private method named mainMenu. mainMenu should display the main menu continually in a loop until the user decides to exit. Menu options include: View Current Balance, Withdraw Money, Deposit Money, and Exit. Exiting the main menu will return control back to main. The other menu options should be implemented as separate private methods Another feature of the ATM is validation of deposits and withdrawals. The ATM should check the account balance before withdrawing and also make sure a positive multiple of 20 is entered. There should be a maximum deposit limit in place. Appropriate error messages should be displayed when the user encounters these limits. From main, use a loop to allow the user to repeatedly log-in to the ATM. Demonstrate the functionality of the ATM class by logging in and out using several IDs and exercising all of the available menu options --> Account ID 11 That account ID doesn't exist. Please try again. Account ID >>5 0:Get Cash Menu Selection >>> 1 Current Balance: $50.00 0:Get Cash 1:View Balance 2:Deposit 3:Exit enu Selection >>> 0 Amout to Withdraw > $55 Error.
