  • Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. This also provides an opportunity to reuse the code functionality and fast implementation time.
  • When creating a class, instead of writing completely new data members and member functions, the programmer can designate that the new class should inherit the members of an existing class. This existing class is called the base class, and the new class is referred to as the derived class.
  • The idea of inheritance implements the is a relationship. For example, mammal IS-A animal, dog IS-A mammal hence dog IS-A animal as well and so on.

Types of Inheritance : :

There are different types of inheritance : :

 
 
  • Single Inheritance
  • Multiple Inheritance
  • Multilevel Inheritance
  • Hierarchical Inheritance
  • Hybrid (Virtual) Inheritance

Below is the source code for C++ program to demonstrate an Example of Single Inheritance which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/* C++ program to demonstrate an Example of Single Inheritance  */

#include<iostream>
using namespace std;
class B
{
    int a;
    public:
    int b;
    void get_ab();
    int get_a();
    void show_a();
};

class D: private B
{
    int c;
    public:
    void mul();
    void display();
};

void B::get_ab()
{
    cout<<"\nEnter Values for a and b :: ";
    cin>>a>>b;
}

int B::get_a()
{
    return a;
}

void B::show_a()
{
    cout<<"\na = "<<a<<"\n";
}

void D::mul()
{
    get_ab();
    c=b*get_a();
}

void D::display()
{
    show_a();
    cout<<"\nb = "<<b<<"\n";
    cout<<"\nc = "<<c<<"\n\n";
}


int main()
{

                        D d;
                        d.mul();
                        d.display();
                        d.mul();
                        d.display();
                        return 0;

}

OUTPUT : :

/* C++ program to demonstrate an Example of Single Inheritance  */

Enter Values for a and b :: 3 4

a = 3

b = 4

c = 12


Enter Values for a and b :: 5 6

a = 5

b = 6

c = 30


Process returned 0

Above is the source code and output for C++ program to demonstrate an Example of Single Inheritance which is successfully compiled and run on Windows System to produce desired output.
