Problem Statement

Create an abstract class `Document` with a pure virtual method `printDoc()`. A class is abstract if it contains at least one pure virtual function, and cannot be instantiated. Create a `PDF` class that implements `printDoc()` by outputting ‘PDF Printed’. Call the method using a pointer.

Input Format

None

Output Format

Print the document status.

Constraints

None

Sample Output

PDF Printed

Explanation

Abstract classes serve solely as strict blueprints. You cannot create objects of them directly.

Starter Code

#include <iostream>

class Document {
public:
    // Make this an abstract class
};

class PDF : public Document {
public:
    // Fulfill the contract
};

int main() {
    // Execute
    return 0;
}
