When the contents of an object cannot be changed after it is created, the object is referred to as mutable.
object that is abstract a variable object Encapsulation
Step by step
Solved in 2 steps
- Programs in which you create and use objects that have attributes similar to their real-world counterparts are known as ____________ programs. procedural logical object-oriented authenticIf the contents of an object cannot be changed once the object is created, the object is called mutable object abstract object mutable object EncapsulationTrue or false: A class object can be passed to a function, but cannot be returned by a function.
- A is a method that is automatically called when an object is instantiated.Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…Object initializers let you assign values to any accessible properties of an object at creation time without having to invoke a constructor Question 19 options: a) True b) False
- Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)…Activity 1 - C++ Language Write a C++ class with the following properties and methods Create a class named BANK ACCOUNT with public properties ACCOUNT NUMBER and BALANCE; - Create a method DEPOSIT that accepts an argument AMOUNT Which stores/add the given AMOUNT in the BALANCE property. - Create a method WITHDRAW that accepts an argument AMOUNT Check the AMOUNT value if less than or equal to the object's BALANCE. Deduct AMOUNT from the current BALANCE if true and return true; Return false if the condition wasn't met. Create a method DISPLAY to show the ACCOUNT NUMBER and current BALANCE of the objectis a construct that defines objects of the same type. A class An object A method A data field
