I need to create an app with sdl2 to use it on Raspbian running outside startix
and be free in the future to use it on other linux operating systems.
The app is a Queue Management System that works in this way:
1) at the start it show the number 00
2) right arrowkey: grow the number of one step, so for exampe ->1 -> 2 -> etc.. till 99
3) left arrow key: reset the number restarting it from 00
