Answer:
// C++ program to demonstrate inheritance
#include <iostream>
using namespace std;
// base class
class Animal {
public:
void eat() {
cout << "I can eat!" << endl;
}
void sleep() {
cout << "I can sleep!" << endl;
}
};
// derived class
class Dog : public Animal {
public:
void bark() {
cout << "I can bark! Woof woof!!" << endl;
}
};
int main() {
// Create object of the Dog class
Dog dog1;
// Calling members of the base class
dog1.eat();
dog1.sleep();
// Calling member of the derived class
dog1.bark();
return 0;
}
