Euro Millionaire Lottery Numbers
================================
This is a Euro Millionaire Lottery Numbers program. In the Euro Millions
Lottery there are two sections: The Lottery Numbers section and the Lucky
Stars section where the user is required to select numbers from each
section. In this project 5 unique random Lottery Numbers are generated
between 1 and 50 inclusive, and also 2 unique random Lucky Stars numbers
are generated between 1 and 12 inclusive. Clicking the User button
generates a set of numbers for the game and these numbers are displayed
on the PC screen.
