What is constructor, destructor, polymorphism, Static function, volatile keyword

Question

Accepted Answer

Constructor initializes an object, destructor cleans up resources. Polymorphism allows objects to be treated as instances of their parent class. Static function belongs to the class, not instances. Volatile keyword indicates a variable may be changed unexpectedly.

Constructor initializes an object when it is created. Example: 'Car c = new Car();'
Destructor cleans up resources when an object is destroyed. Example: 'delete ptr;'
Polymorphism allows a child class to be treated as an instance of its parent class. Example: 'Animal a = new Dog();'
Static function belongs to the class, not instances. Example: 'Math.max(5, 10);'
Volatile keyword indicates a variable may be changed unexpectedly. Example: 'volatile int x = 10;'
