class Person {
  public name: string; // Public property (default if not specified)
  private age: number; // Private property
  protected email: string; // Protected property

  constructor(name: string, age: number, email: string) {
    this.name = name;
    this.age = age;
    this.email = email;
  }

  // Public method (default if not specified)
  introduce(): void {
    console.log(`Hi, I'm ${this.name}, and I'm ${this.age} years old.`);
  }

  // Private method
  private sendEmail(): void {
    console.log(`Email sent to ${this.email}`);
  }

  // Protected method
  protected getAge(): number {
    return this.age;
  }
}

class Employee extends Person {
  // Inherited properties can be accessed in subclasses
  showAge(): void {
    console.log(`Age: ${this.getAge()}`);
  }
}

// Creating an instance of the Person class
const person = new Person('John', 30, 'john@example.com');

// Accessing public properties and methods
person.name = 'Jane';
person.introduce();

// Accessing private and protected members will result in an error
// person.age; // Error: Property 'age' is private
// person.email; // Error: Property 'email' is protected
// person.sendEmail(); // Error: Property 'sendEmail' is private

// Creating an instance of the Employee class
const employee = new Employee('Alice', 25, 'alice@example.com');

// Accessing protected method through subclass
employee.showAge(); // Output: Age: 25
// employee.getAge(); // Error: Property 'getAge' is protected
