Challenge 2: Implement a Class Using Pure Virtual Functions

Problem Statement

Write a code that has:

• A parent class named Account.
  • Inside it define:
    • a protected float member balance
  • We have three pure virtual functions:
    • void Withdraw(float amount)
    • void Deposit(float amount)
    • void printBalance()

• Then, there are two derived classes
  • Savings class
    • has a private member interest_rate set to 0.8
    • Withdraw(float amount) deducts amount from balance with interest_rate
