Click on "Show Answer" to reveal the answer.
1. Create a simple base class `Animal` with a method `Speak()`. Derive a `Dog` class that overrides it.
Max Time: 5 minutes
Explanation: This introduces basic inheritance. The `Dog` class will override the `Speak()` method of the `Animal` class.
2. Create a `Person` class with a method `GetDetails()`. Derive a `Student` class that overrides it.
Max Time: 8 minutes
Explanation: You'll learn how a derived class (`Student`) can provide a different implementation of a method inherited from the base class (`Person`).
3. Implement an `Employee` base class with a method `CalculateSalary()`. Create a `Manager` class that adds a bonus to salary.
Max Time: 10 minutes
Explanation: This question introduces method overriding and the use of `base` to call the parent class method while adding additional logic.
4. Create a `Vehicle` class with `StartEngine()`. Extend it to `Car` and `Motorcycle` with different behaviors.
Max Time: 12 minutes
Explanation: This demonstrates how multiple classes can inherit from the same parent and implement methods differently.
5. Implement a `BankAccount` class with `Deposit()` and `Withdraw()`. Extend it to `SavingsAccount` with interest calculation.
Max Time: 15 minutes
Explanation: You'll implement a basic banking system where `SavingsAccount` adds extra functionality.
6. Implement `Shape` class with `CalculateArea()`. Extend to `Rectangle` and `Circle` with area calculations.
Max Time: 15 minutes
Explanation: You'll learn how different classes can provide unique implementations for a common method.
