what does the ampersand (&) mean
what does * mean
those are very basic C++ concepts.
It looks like you need to improve your C++ skills before jumping into Qt framework.
What is your C++ level ?
I am asking this because your questions are about basic concepts of the language.
The ampersand means a reference and the star a pointer. If don't know either, you should first learn the basics before going any further.
