I haven't read these 2 books, but would like the opinion of someone who did.
[1] C Interfaces and Implementations: Techniques for Creating Reusable Software by David Hanson - HN's tptacek seemed to rave about this book, that's how I heard of it. Wonder what he thinks of it in 2021.
[2] C Programming: A Modern Approach by K. N. King - this one seems to be loved by many. Seems to be more 'beginner-friendly' than the 1st one I guess.
Is it possible to download free apps from the App Store without ever giving payment details to Apple? For example, if I don't set up card details during phone set up, can I still download free apps?
Edit: Here's a short rationale for the book by the author.
