class User {
    public $name;
    private $email;
    
    public function __construct($name, $email) {
        $this->name = $name;
        $this->email = $email;
    }
    
    public function getEmail() {
        return $this->email;

class Admin extends User {
    public function deleteUser($id) {
        // Admin-specific functionality
    }
}
