Multiple inheritances in C++ language

In this tutorial, we will discuss the OOP concept of multiple inheritances in C++ language.

Inheritance is the process of inheriting data members and methods of one class by another class. When a class is derived from two or more base class, it is called multiple inheritance. Multiple inheritance is a feature of the object-oriented programming language of C++.

In C++, a child class can inherit from more than one parent class. Multiple inheritance is not support in Java.

Syntex

class A

{

””””””””””””””””

};

class B{

………………………

}

class C access_specifier A, acces_Specifier B//inherit properties from classes A and B

Program 1

Explanation is above program

#include <iostream>
using namespace std;
class cost //start of class cost
{
protected://access modifier – protected
int cp;
public://access modifier – public
void getcp()
{
cout << “Enter the cost prize:” << endl;
cin >>cp;
}
}; //end of class cost
class sell
{ //start of class sell
protected: //access modifier – protected
int sp;
public:
void getsp()
{
cout << “Enter the selling prize:” << endl;
cin >>sp;
}
}; //end of class sell

class profit:cost,sell
{ //start of class profit and which is inherits property from parant class cost, sell
private: //access modifier – private
int pf;
public: //access modifier – public
void profits()
{
getcp();
getsp();
pf=sp-cp;
cout << “profit is:” <<pf<<endl;
cin >>sp;
}
}; //end of class profit
int main()
{
profit o; //create object for class profit
o.profits(); //call method profit through object
return 0;
}
