Create classes `Student`, `Test`, `Sports`, and `Result` to demonstrate hybrid inheritance. Accept data and display total marks.

#include <iostream>

    void showStudent() {
        cout << "Roll No: " << roll << endl;
        cout << "Name: " << name << endl;

// Derived Class: Test (from Student)
