Employee Class in C++ for Salary Calculation

This C++ snippet defines an Employee class that manages employee attributes such as name, number, position, marital status, daily wage, and overtime details. It includes methods to calculate overtime pay and gross salary, demonstrating basic class structure and member functions in C++.
