Do I need to worry about gunking up my computer by messing around with this type of programming? I have very limited knowledge of programming just from an intro to Java class, and I've never programmed in Pascal's version (is this C++?). I heard some programming languages create 'garbage' in your memory, so I was wondering if I need to be cognisant of that or anything else pertaining to potentially messing up my computer while I play around with these tutorials.
