Multiple Inheritance in C++

In C++, multiple inheritance is a feature that allows a class to inherit properties and behavior from multiple classes. This means that a class can have multiple base classes, and it can inherit properties and behavior from all of them.

Here is an example of multiple inheritance in C++:

#include <iostream>

using namespace std;

// Base class A
class A {
int a;
void displayA() {
cout << "Value of a: " << a << endl;

// Base class B
class B {
int b;
void displayB() {
cout << "Value of b: " << b << endl;

// Derived class C, which inherits from both class A and class B
class C : public A, public B {
int c;
void displayC() {
cout << "Value of c: " << c << endl;

int main() {
C obj;
obj.a = 10;
obj.b = 20;
obj.c = 30;
return 0;

In this example, class C is the derived class, and it inherits from both class A and class B. This means that it has access to the a and b variables and the displayA() and displayB() functions from both base classes. It also has its own c variable and displayC() function.

When the displayA(), displayB(), and displayC() functions are called on an object of class C, they will print the values of the a, b, and c variables, respectively.
