Multiple Inheritances

Multiple Inheritance: 

Very often situations may arise in which a class has to derive features from more than one class. Multiple inheritance facilitates a class to inherit features from more than one class. The derived class can access two or more classes and can add properties of its own.

Write a program to explain multiple inheritances Algorithm:

step1:Take three classess student, employee, manager

step2:with in a student class Enter name and school, college data with the help of getdata() function and display this data using putdata() function.

step3: within the employee class Enter and display company, age data with the help of getdata(),putdata() functions.

step4: within the Programmer class extends student and employee classess and using data and their functions to the Programmer class and Enter & display disegnation , salary of the Programmer using putdata(),getdata() functions

step5:within the main function create instance of Programmer class ‘m’ and call getdata() and putdata() functions.

Program Code:

#include<iostream.h>

#include<conio.h>

const int MAX=50;

class student

{

private:

char name[MAX];

char school[MAX];

char college[MAX];

public:

void getdata()

{

cout<<”\n \t Enter name :”;

cin>>name;

cout<<”\t Enter school name:”;

cin>school;

cout<<”\n \t Enter College name:”;

cin>>college;

}

void putdata()

{

cout<<”\n \t Name :”<<name;

cout<<”\n \t School Name :”<<school;

cout<<”\n \t College Name :”<<college;

}

};

class employee

{

private

char company[MAX];

Int age;

public :

void getdata()

{

cout<<”\n \t Enter the company name :”;

cin>>company;

cout<<”\n \t Enter age:”;

cin>>age;

}

void putdata()

{

cout<<”\n \t Company Name :”<<company;

cout<<”\t Age:”<<age;

}

};

class Programmer : private employee,private student

{

private:

char design[MAX];

Float salary;

public :

void getdata()

{

Student ::getdata();

Employee ::getdata();

cout<<”\n \t Enter your Designation :”;

cin>>design;

cout<<”\n \t Enter salary:”;

cin>>salary;

}

void putdata()

{

Student ::putdata();

Employee::putdata();

cout<<”\n \t Designation :”<<design;

cout<<”\n \t Salary :“<<salary;

}

};

void main(0

{

Programmer m;

cout<<”\n Enter data for Programmer:”<<endl;

m.gatdata();

cout<<”\n The data for Programmer is :”<<endl;

m.putdata();

}

Output:

Enter data for Programmer :

Enter name : Raja

Enter name of school: GSSCB

Enter name of college :GCH

Enter name of company :CU

Enter age :34

Enter designation : Programmer

Enter salary : 25000

The data for Programmer is

Student Name :Raja

School Name :GSSCB

College Name :GCH

Company Name :CU

Age :34

Designation :Programmer

Salary:25000
