Is there some game or interactive way to learn about code language and linux (on Raspberry)? Messing with Raspberry the curiosity itch caught my back and I can't scratch enough. I don't wanna just copy texts and press enter, but know why make such decisions.
I don't know if I made myself clear, thanks in advance.
IMHO the BEST C book is: C How to Program by Deitel. It also covers secure programming and C++. C Programming Language by Ritchie Dennis is also a great book but not for beginners. Avoid the for Dummies books, they're horrible.
Bjarne Stroustrup has written a couple C++ books, they're considered one of the best C++ books. I have them in eBook format but I'm still on the Deitel book.
Most emulators are written in C/C++, the Pi supports C/C++, Linux was written in C. So IMHO better start with C and later C++ and good luck with your coding journey, it will be a lot of fun!
