Polymorphism in C++ is an object-oriented programming concept that allows objects to be treated as instances of their parent class rather than their actual class. It enables a single interface …

Abstraction in C++ is an object-oriented programming principle that focuses on hiding the complexity of the system by exposing only essential information. By providing only relevant details and hiding unnecessary …

In C++, encapsulation is an object-oriented programming principle that combines data (attributes) and functions (methods) into a single unit called a class. Encapsulation helps control access to the data by …

In C++, a destructor is a special member function that is called automatically when an object goes out of scope or is explicitly deleted. The primary role of destructors is …

Constructors in C++ are special member functions that are automatically called when an object of a class is created. They initialize the object’s data members and allow setting up initial …
