Slot Machine Game

/* This code is originally written by me for the example of my tutorials
which you can check on my website. If you ask why am I not using Array, Maps, Class
or another functions in C++, it's because my tutorial hasn't reach that part. But if you
want to change the code using other functions it's better! :)

Enjoy this simple Slot Machine Game
