Inheritance is one of the great feature in Object Oriented Programming. Ruby supports inheritance. Inheritance allows to inherit the features of the base classes to its derived classes. That means, through derived class objects we can access the features of the base class. Through this Article, we will discuss how we use Inheritance in Ruby. […]
‘C#’ class members are accessible based on their access specifiers. I will write a separate article on class’s access specifiers in more detail. But here I want to give an high level introduction on access specifiers. Access Specifiers ‘C#’ provides public, private, internal, protected and protected internal access specifiers. Remember that the class members are […]
Inheritance allows reusing the functionality. Inheritance inherits base class members to its derived class. We can use base class members within the derived class without rewriting the base class code. C++ allows single inheritance as well as multiple inheritances. In single inheritance, the derived class is inherited from a single base class. In multiple inheritances, […]
In C++, class constructors are special kind of methods to instantiate a class. When the class’s object is going to create, C++ will first call the class’s constructor to initialize the class. Initializing the class means, assigning its members and allocating any dynamic memory, etc., After the class’s constructor is called, the class’s object creation […]
An interface is a contract between a caller and a callee. An interface doesn’t provide any implementation. It provides a blueprint. C++ uses a virtual keyword to create an interface or an abstract class. Let’s take an example: class IHello { public: virtual void SayHello() = 0; }; IHello is an interface with the SayHello […]
C++ is a Object Oriented language. C++ uses virtual keyword in different places. One of the use of virtual keyword is to create virtual functions. An important feature in Object Oriented programming is Polymorphism; which means multiple-behaviors. An object has multiple behaviors and it shows particular behavior depending on its context. C++ achieves this with […]
