在本章中,我们将完全用C语言,实现面向对象中最重要的几个概念,分别是继承,覆盖。我们先看实现后的调用: int main (int argc, char ** argv) { void * p; while (* ++ argv) { switch (** argv) { case &#…

Private Simple Inheritance Program in C++// C++ program to demonstrate example of // private simple inheritance #include <iostream> using namespace std; class A { private: int a; protected: int x; // Can access by the derived class public: void setVal(int v) { x = v;...
Constructors and Destructors in Inherited Classes A constructor is a special function that gets called when an object is created. A destructor is called when an object is about to be destroyed (usually when the program ends). Inherited classes can use both the base class’s constructor and des...

In the above diagram, Class X contains member A and B. Later on, if a Class Y is to add to the program. Which has identical members A and B to that of Class X along with an additional member C. Then instead of writing the code for members A and B again in Class Y. It is be...

Explanation:From the above program and output we can infer how actually hierarchical inheritance works in terms of C++. Class X is the single base or parent class that has its own properties as well as some common properties as the base class and methods as well. Therefore, the base class ...
