Various forms of inheritance in C++ with necessary coding

The various forms of inheritance in C++ with necessary coding.

INHERITANCE:

•  Inheritance is a mechanism of deriving a new class from a old class.

•  It provides the concept of reusability

•  By inheritance some or all the properties of a class can be derived in to another class.

•  The class which provides the properties is called as base class and the class which

derives the properties is called as derived class.

Types:

There are five types of inheritance viz

1. Single level inheritance

2. Multiple inheritance

3. Multilevel inheritance

4. Hybrid inheritance and

5. Hierarchical inheritance

Multiple inheritance:

It is a type of inheritance in which a class can inherit properties from more than one class.

Syntax:

Class derivedclass name : visibility mode baseclass1,visibilitmode baseclass2

{

body of the derived class;

};

visibility mode can be either private or public.

Example :

#include

#include

class bc1

{

protected:

int a; public :

void get()

{

cout <<”\n enter the value for a\n”; cin >>a;

}

};

class bc2

{

protected:

int b;

public;

void get1()

{

cout <<” \n enter the value for b \n”; cin>>b;

}

};

class dc : public bc1, public bc2

{

public :

void show()

{

cout <<”The values of a and b are” ; cout <<<”\n”<

}

};

void main()

{

clrscr();

dc d;

d.get();

d.get1();

d.show();

}

output:

Enter the value for a 20

Enter the value for b 30

The values of a and b are 20 30
