>>7838281video/blog tutorials are good if you just want to learn how to do one specific thing
books/manuals explain not just how to use something like a programming language, but also how it works internally, which makes it much easier to learn things in the future and allows you to make connections between the things you learn
if you just saw on some website that you have to copy three magic lines of code to use `malloc`, then you won't really understand what it's doing enough to change it to make it work in a different scenario. there's no way to understand pointers from a tutorial because they're only used, never explained. they don't need to be because you'd never need to ask a question about them to learn about them -- other than, "how does this code do what it does?", and to find that answer you'll have to look in a manual
