Multiple, Multilevel, Hybrid and Hierarchical inheritance

-

Multiple inheritance: 

                        Multiple inheritance is a type of inheritance in c++ in which a class can be inherited from more than one classes. In this case the inherited class has more than one parent class.


Multiple inheritance example:
       

#include <iostream>
using namespace std;
class Animal
{
public:
   Animal(){ cout<<" Animal's constructor "<<endl;}
};
class Mammal
{
public:
   Mammal(){cout<<" Mammal's constructor"<<endl;}
};
class Bat: public Animal,public Mammal
{
public:
  Bat(){ cout<<" Bat's constructor "<<endl;}
};
int main(){
    Bat bat1;
   return 0;
}

Output:
Animal's constructor
Mammal's constructor
Bat's constructor

Multilevel inheritance:

           In multilevel inheritance a class can be derived from another class who is already defined from another class.

Example of multilevel inheritance:

#include <iostream>
using namespace std;
class Animal
{
public:
   Animal(){ cout<<" Animal's constructor "<<endl;}
};
class Mammal: public Animal
{
public:
   Mammal(){cout<<" Mammal's constructor"<<endl;}
};
class Bat: public Mammal
{
public:
  Bat(){ cout<<" Bat's constructor "<<endl;}
};
int main(){
    Bat bat1;
   return 0;
}

Output:
Animal's constructor
Mammal's constructor
Bat's constructor

Hierarchical inheritance:

         When several classes are derived from common base class it is called hierarchical inheritance. 

Hierarchical inheritance example:


#include <iostream>
using namespace std;
class ClassRoom
{
public:
   ClassRoom(){ cout<<" ClassRoom constructor "<<endl;}
};
class Grade4Class: public ClassRoom
{
public:
   Grade4Class(){cout<<" Grade4Class constructor"<<endl;}
};
class Grade9Class: public ClassRoom
{
public:
  Grade9Class(){ cout<<" Grade9Class constructor "<<endl;}
};
class Grade10Class{
public:
  Grade10Class(){ cout<<" Grade10Class constructor"<<endl;}
};
int main(){
    Grade4Class Student1;
   return 0;
}

Output:
ClassRoom constructor
Grade4Class constructor

Hybrid inheritance:

            Hybrid inheritance, also called multipath inheritance, is the process of deriving a class using more than one level or more than one mode of inheritance.
It can be considered as the mixture of all types of inheritance.

Virtual function in c++

-
Virtual Function: Virtual means existing in effect but not in reality. A type of function that appears to exist in some part of the program but does not exist really is called a virtual function. Virtual functions are used to implement polymorphism. They enable the user to execute completely different functions by the same function call. A virtual function is defined in the parent class and is overridden in child classes. It is defined by the keyword virtual. If you want to call a virtual function in C++ and execute the redefined version of the member function, you can achieve this task using a pointer or a reference ( -> ) by referring a derived class object to the base class. A base class pointer has the capability to point to the objects of the base class and the derived class. But it's converse is not true. An example of using virtual function with reference: #include<iostream> using namespace std; class Animal {     public:         virtual ...

Practice problem classes and objects.

        Creating classes and objects in C++ Problem:        Create a class named ClassRoom  that has 6 private  member variables named t otalChairs, totalTables, classGrade, teacherName, totalStudents and  classRep. Your class must have 2  public member functions named as input and  output. These two input and output functions will work as getter and setter. You must also create a constructor that initializes the values of all the private member variables to null or 0. Remember: We can use any name for our getter and setter function. Now for our main method create an object of our class ClassRoom named Class1. Input values from the user by calling the Input function of the object Class1. Then output all the values. All the above conditions must be fulfilled. Visit here for reference about classes and objects: C++ classes and objects
