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). Thepin should be generated randomly when the account object is created. The initial balance shouldbe 0.get_pin()should return the pin.check_pin(pin) should check the argument against the saved pin and return True if itmatches, False if it does not.deposit(amount) should receive the amount as the argument, add the amount to the accountand return the new…

- Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (p. 479). Kindle Edition. 9. Write a program named SalespersonDemo that instantiates objects using classes named RealEstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each object’s data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salesperson’s full name—the first and last names separated by a space. Then perform the following tasks: • Create two child classes of Salesperson: RealEstateSalesperson and GirlScout.
