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
      • Deposit(float amount) adds amount in balance with interest_rate
      • printBalance() displays the balance in the account
  • Current class
    • Withdraw(float amount) deducts amount from balance
      • Deposit(float amount) adds amount in balance
      • printBalance() displays the balance in the account`

Input

• In Savings class, balance is set to 50000 in parametrized constructor of Savings object called by Account class
• In Current class, balance is set to 50000 in parametrized constructor of Current object called by Account class

Here’s a sample result which you should get.

Sample Input

  Account * acc[2];
  acc[0] = new Savings(50000);  
  acc[0]->Deposit(1000);
  acc[0]->printBalance();
  
  acc[0]->Withdraw(3000);
  acc[0]->printBalance();
  
  acc[1] = new Current(50000);
  acc[1]->Deposit(1000);
  acc[1]->printBalance();
  
  acc[1]->Withdraw(3000);
  acc[1]->printBalance();
