Data abstraction refers to providing only essential information to the outside world and hiding their background details, i.e., to represent the needed information in program without presenting the details. Data abstraction is a programming (and design) technique that relies on the separation of interface and implementation. Let’s take one real life example of a TV,…

The word polymorphism means having many forms. Typically, polymorphism occurs when there is a hierarchy of classes and they are related by inheritance. C++ polymorphism means that a call to a member function will cause a different function to be executed depending on the type of object that invokes the function. Consider the following example where a…

C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively. An overloaded declaration is a declaration that is declared with the same name as a previously declared declaration in the same scope, except that both declarations have different arguments and obviously different definition (implementation).…

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 functionality and fast implementation time. When creating a class, instead of…

Multilevel inheritance is a type of inheritance, where a class is derived from another derived class, creating a chain of inheritance that allows it to pass down its properties and behaviors through multiple levels of classes or inherit from its predecessor. Implementing Multilevel Inheritance To implement multilevel inheritance, define classes in a hierarchical manner, where…

Multiple inheritance in C++ is a feature that allows a class to inherit from more than one base class, which means a derived class can have multiple parent classes and inherit attributes and behaviors from all the base classes. Implementing Multiple Inheritance To implement multiple inheritance, you need to specify multiple base classes in the derived…

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. A class is used to specify the form of an object and it combines data representation and methods for manipulating that…

The prime purpose of C++ programming was to add object orientation to the C programming language, which is in itself one of the most powerful programming languages. The core of the pure object-oriented programming is to create an object, in code, that has certain properties and methods. While designing C++ modules, we try to see…

A function is a collection of code blocks with instructions inside, which is used for specific tasks. It is meant to be reused as per requirement, making the division of complex problems into smaller and manageable pieces. What is Function Overriding in C++? Function overriding is a concept of object-oriented programming which allows a derived class…

Function overloading in C++ allows you to define multiple functions with the same name but different parameters. Function overloading is used to achieve polymorphism which is an important concept of object-oriented programming systems. Syntax for Overloaded Functions Consider the following two function declarations having the same name but different parameters − Example of Function Overloading In…
