Project 4: Banking System

Build a Banking System

Bring together classes, inheritance, and exception handling to model a simple bank. You'll have a base Account class and a SavingsAccount that extends it.

YOUR TASK

Create a program that:

Defines a BankAccount class with Owner and Balance
Has Deposit(double amount) and Withdraw(double amount) methods
Throws an exception if withdrawal exceeds balance
Defines a SavingsAccount that inherits BankAccount and adds InterestRate
Has an ApplyInterest() method that increases balance by the rate
Demonstrates: deposit, withdraw, interest, and a failed overdraft

Need a hint?

Structure:
1. class BankAccount { public string Owner; public double Balance; }
2. In Withdraw: if (amount > Balance) throw new Exception("Insufficient funds");
3. class SavingsAccount : BankAccount { public double InterestRate; }
4. ApplyInterest: Balance += Balance * InterestRate;
5. Use try/catch around the overdraft attempt

Expected output:

Deposited $500. Balance: $500.00
Withdrew $200. Balance: $300.00
Interest applied. Balance: $315.00
Error: Insufficient funds
