## What people are saying about Notes for Professionals books

Looks like there is a great book about C++ available for free. Checked it and it seems like a definitive guide. Worth seeing https://books.goalkicker.com/CPlusPlusBook/ #cpp #programming

This is really cool! Thanks a lot! Genius of place pdf free download.

A lot of effort went into this, I also took a look at the languages I'm familiar with. They even have screenshots of the results and provide an excellent way of showing exactly what you would input and see. I really appreciate the fact that they are pdf that you can save and don't have to rely on an internet connection.

Thanks, Great Collection.
