Program Of Multiple Inheritance In C++

#include<iostream.h>

#include<conio.h>

class base

{

private:

int a;

public:

void getdatab(int x)

{

a=x;

}

void displayb()

{

cout<<"\n base value is="<<a;

}

} ;

class derive

{

private:

int b;

public:

void getdatad(int y)

{

b=y;

}

void displayd()

{

cout<<"\n derive value is="<<b;

}

} ;

class derive1 : public base, public derive     // Multiple Inheritence

{

private:

int c;

public:

void getdatad1(int z)

{

c=z;

}

void displayd1()

{

cout<<"\n derive1 value is="<<c;

}

} ;

main()

clrscr();

derive1 d1;

d1.getdatab(5);

d1.getdatad1(9);

d1.displayb();

d1.displayd();

Define Multiple Inheritance

Deriving directly from more than one class is usually called multiple inheritance. Since it's widely believed that this concept complicates the design and debuggers can have a hard time with it, multiple inheritance can be a controversial topic. However, multiple inheritance is an important feature in C++ and C++ programmers think of it as a very good structuring tool.
