Program code demonstrating inheritance

#include <iostream>
using namespace std;
// Parent class
class Animal {
public:
void eat() {
cout << “The animal of this class will eat: mnyaa! mnyaa!mnyaa!” << endl;
}
void sleep() {
cout << “The animal of this class will sleep” << endl;
}
};
// Child class
class Dog : public Animal {
public:
void bark() {
cout << “The Dog will bark: wo!wo!wo!” << endl;
}
};
int main() {
// This will create an object of the child class
Dog thisDog;
// This will call methods from the parent class
thisDog.eat();
thisDog.sleep();
// This will call method from the child class
thisDog.bark();
return 0;
}
