Fundamentals of Object-Oriented Programming - C++ - UML Abstract Class - ATM Part 1

The video tutorial covers creating a simple ATM simulation program using a UML model. It explains the inheritance hierarchy with a base Account class and derived Savings and Checking Account classes. The Account class tracks balance and transactions, with methods for deposits and withdrawals. The Savings Account includes interest calculation, while the Checking Account applies fees for transactions. The Transaction class records transaction details. The tutorial also demonstrates implementing these classes in Code Blocks, focusing on constructors, methods, and operator overloading.

What is the primary purpose of the UML model in the ATM simulation program?

• To define the user interface

• To describe the network architecture

• To specify the database schema

• To outline the class structure and relationships

Which method in the Account class is responsible for returning the current balance?

• calculateInterest

• withdraw

• getBalance

• printBalance

What additional attribute is introduced in the Savings Account class?

• Interest rate

• Transaction fee

• Overdraft limit

• Minimum balance

In the Checking Account class, what is the purpose of the fee attribute?

• To calculate interest

• To charge for transactions

• To set a minimum balance

• To track overdrafts

What is the first step in creating classes in the code blocks editor?

• Implementing methods

• Defining class attributes

• Creating header files

• Clicking on 'File' and 'New Class'

What is the purpose of overloading the plus operator in the Account class?

• To multiply balances

• To add balances of two accounts

• To divide balances

• To subtract balances

Which method in the Account class checks if there are sufficient funds for a withdrawal?

• printBalance

• getBalance

• withdraw

• deposit

What is the return type of the deposit method in the Account class?

• bool

• double

• int

• void

What happens if there are insufficient funds during a withdrawal attempt?

• The method returns false

• The transaction is completed

• The balance is updated

• The method returns true

What is the purpose of the report method in the Account class?

• To charge a fee

• To print a list of transactions

• To calculate interest

• To update the balance
