Challenge 3: Implement a Banking Application Using Polymorphism

Problem Statement

Write a code that has:

• A base class named Account.

  • Inside it define:
    • A field, private double _balance
    • A protected property, Balance, to access the balance
    • public virtual bool Withdraw(double amount)
    • public virtual bool Deposit(double amount)
    • public virtual void PrintBalance()

• Then, there are two derived classes

  • SavingsAccount class has:

    • A private field _interestRate set to 0.8

    • An overridden Withdraw() method that deducts amount from balance with interestRate only if enough balance is available. The withdrawal amount should be greater than zero.

      • Returns true if the transaction was successful and false otherwise.

    • An overridden Deposit() method that adds amount to balance with interestRate and also checks if the amount to be deposited is greater than zero

      • Returns true if the transaction was successful and false otherwise.

    • PrintBalance() displays the balance in the account

  • CheckingAccount class has:

    • An overridden Withdraw() method that deducts amount from balance only if enough balance is available and the withdrawal amount should be greater than zero

      • Returns true if the transaction was successful and false otherwise.

    • An overridden Deposit() method that adds amount in balance and also checks if the amount to be deposited is greater than zero

      • Returns true if the transaction was successful and false otherwise.

    • PrintBalance() displays the balance in the account

For SavingsAccount:
