Hybrid inheritance is done when we have to mix different types of inheritance within a single program, for example, mixing single inheritance with multiple inheritance or multiple inheritance within a single program.

In the above diagram, Class B and Class C are derived from the base class A.
Example-

In the above figure, a hierarchical classification of birds is shown. Here there are two derived classes 'Non-Flying Bird' and 'Flying Bird' accesses the members of one base class 'Bird'.

Example Code

#include<iostream>
#include<conio>
using namespace std;
class arithmetic
{
    protected:
    int num1, num2;
    public:
    void getdata()
    {
        cout<<"For Addition:";
        cout<<"\nEnter the first number: ";
        cin>>num1;
        cout<<"\nEnter the second number: ";
        cin>>num2;
    }
};
class plus:public arithmetic
{
    protected:
    int sum;
    public:
    void add()
    {
        sum=num1+num2;
    }
};
class minus
{
    protected:
    int n1,n2,diff;
    public:
    void sub()
    {
        cout<<"\nFor Subtraction:";
        cout<<"\nEnter the first number: ";
        cin>>n1;
        cout<<"\nEnter the second number: ";
        cin>>n2;
        diff=n1-n2;
    }
};
class result:public plus, public minus
{
    public:
    void display()
    {
        cout<<"\nSum of "<<num1<<" and "<<num2<<"= "<<sum;
        cout<<"\nDifference of "<<n1<<" and "<<n2<<"= "<<diff;
    }
};
int  main()
{
    result z;
    z.getdata();
    z.add();
    z.sub();
    z.display();
    return 0;
}

Output:

For Addition

Enter the first number:10
Enter the second number:5

For Subtraction:

Enter the first number:10
Enter the second number:5

Sum of 10 and 5= 15
Difference of 10 and 5= 5
