Question: Define constructor and destructor in object-oriented programming languages and provide examples. Answer: A constructor is a special member function of a class that is executed when an object of that class is created. Constructors are used to initialize the object's attributes and allocate resources. In most programming languages, constructors have the same name as the class and no return type. A destructor is another special member function of a class that is executed when an object of that class is destroyed. Destructors are used to clean up resources and perform cleanup tasks. In most programming languages, destructors have the same name as the class, prefixed with a tilde (~) and no return type. Example: In a Car class with "brand" and "model" attributes, the constructor initializes these attributes, and the destructor performs cleanup tasks when a car object is destroyed. ```cpp class Car { public: Car(std::string _brand, std::string _model): brand(_brand), model(_model) { } ~Car() { // Perform cleanup tasks here } private: std::string brand; std::string model; }; Car myCar("Toyota", "Camry"); // Constructor usage ```
