It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the data member as pointer to object of similar class, then it is called a self-referential class.
Checking Object Type in Polymorphism: In situations where base class pointers can point to objects of various derived classes,dynamic_castcan be used to determine the actual type of the object being pointed to. Return Value: If the cast is successful with pointers,dynamic_castreturns a pointer...
A Destructor in C++ is a member function having the same name as that of the constructor. But, it is preceded by a tilde (~) symbol.
The Curiously Recurring Template Pattern (CRTP) is a form of compile-time polymorphism which allows you to extend types with common pieces of functionality without paying the runtime costs of virtual functions. This is sometimes referred to as mixins (this isn’t all the CRTP can be used for...
Modern C++ uses template-based static polymorphism (very similar to OCaml's parametric polymorphism) in place of inheritance and dynamic dispatch, and uses value semantics and move semantics to reduce sharing (and thus cross-thread sharing) of mutable data. (Note that move semantics is not ...
What is Instructions in C++ By Dinesh Thakur There are many different types of Constants variables and Keywords in c++ Language. There are basically four types of Instructions in C++. Ø Type Declaration Instructions Ø Input/output Instructions Ø Arithmetic Instructions Ø Control Instruction...

Define polymorphism and how is used in OOP. What is the difference between int and Int in a java program? Use CPP to complete and explain the following: Consider the following class declaration and answer the following. a) Write the function definition for the overloaded + operator that will...
