Now the topic of mobile application development is relevant. For my company, I also searched for a developer some time ago. I was helped by the reviews. mobile apps development for my company was conducted by openGeeksLab https://opengeekslab.com/mobile-development/. I liked the approach of openGeeksLab specialists. New development trends have been taken into account

The C Programming Language By Brian W. Kernighan and Dennis M. Ritchie is imo still the best book around. It's quite old but one of its authors is the very creator of the language.and the book in general is incredibly well written and has a ton of exercises.
