Decision Statement ,Array Structure and Pointers In C++if (condition)  {   stmt 1;  //Executes if Condition is true } else {   stmt 2;  //Executes if condition is false } switch(var)  { case 1:  //if var=1 this case executes   stmt;   break; case 2…[ More ]

Interfaces:   An interface describes the behavior or capabilities of a C++ class without committing to a particular implementation of that class. The C++ interfaces are implemented using abstract classes and these abstract classes should not be confused with data abstraction which is …[ More ]

Inheritance:   One of the most important concepts in object-oriented programming is that of inheritance. Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. This also provides an opportunity to reuse the code func…[ More ]

Constructor & Destructor The Class Constructor:   A class constructor is a special member function of a class that is executed whenever we create new objects of that class.   A constructor will have exact same name as the class and it does not have any return type at all, not ev…[ More ]

Classes and Objects   The main purpose of C++ programming is to add object orientation to the C  programming language and classes are the central feature of C++ that supports object-oriented programming and are often called user-defined types. C++ Class Definitions:   When y…[ More ]

Overview of C++ C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and…[ More ]
