In this article we will learn how to implement a pure virtual function program in C++. A C++ program is provided to illustrate the concept of pure virtual function and calculate the area of different shapes by using abstract class. Program is as follows: #include <iostream> using namespace std; class Shape { public: virtual void […]
In this article we will try to implement a CPP program to show how constructors are invoked in derived class. A C++ program is given below to demostrate how constructors are invoked in derived class. Program is as follows: #include <iostream> using namespace std; class A { protected: int x; public: A(int p) { […]
In this article we will learn to implement a CPP program to illustrate the order of execution of constructors and destructors in inheritance. A C++ program is provided below to demonstrate in which order constructors and destructors are executed in inheritance. Program is as follows: #include <iostream> using namespace std; class A { public: […]
In this article we will learn to implement a CPP program to implement virtual base class. A C++ program is provided below to illustrate virtual base class. Program is as follows: #include <iostream> using namespace std; class A { protected: int x; }; class B : virtual public A { private: int y; public: […]
