Basic Example using Multiple Inheritance in C++

This program demonstrates how to create multiple base classes using multiple inheritance in C++. Here, we have three classes: A, B, and C. A and B are base classes and C is a derived class that inherits from both A and B. In the main() function, an object of C class is created using the default constructor. When the object is created, first the A class constructor is called followed by the B class constructor and then the C class constructor.

Source Code

#include<iostream>
using namespace std;
class A
{
   public:
    A()
    {
       cout<<"Constructor of A class"<<endl;
    }
};
class B
{
   public:
    B()
    {
       cout<<"Constructor of B class"<<endl;
    }
};
class C: public A, public B
{
   public:
    C()
    {
       cout<<"Constructor of C class"<<endl;
    }
};
int main()
{
  C obj;
  return 0;
}
