Problem Statement

Create a base class `Animal` with a virtual method `void speak()` that prints ‘Animal’. Create a derived class `Dog` that overrides `speak()` to print ‘Dog’. In `main()`, create a `Base` pointer, assign it the address of a `Dog` object, and call `speak()`.

Input Format

None

Output Format

Print the output of the overridden method.

Constraints

None

Sample Output

Dog

Explanation

The virtual keyword tells the compiler to resolve the method call at runtime based on the actual object type, not the pointer type.

Starter Code

#include <iostream>

class Animal {
public:
    // Write your virtual method here
};

class Dog : public Animal {
public:
    // Override speak() here
};

int main() {
    // Create pointer, assign Dog object, and call speak()
    return 0;
}
