Is it worth focusing on an incomprehensible topic?

Question

C++ / C#

Hello.
While learning C++ and reading my almost first book, I came across a topic that I didn't understand. A function that returns a pointer to an array, as well as something incomprehensible with a vector (a vector function parameter) and something else from what is from the list of new standards. So, should I dwell on this now and is it true that if I don’t understand it now, I will never understand it? Naturally, after reading Lippmann's 1000-page textbook, I'm going to read separately about OOP, STL, and so on.

Answer 1

Be more flexible. A little theory, a little practice. No need to rush absolutely everything and everything to cram and memorize. Write! I assure you that you will quickly realize how much you have mastered the material that you have just read, if you immediately start writing something and try to apply it without delay. Programming is an art, sometimes some logical things don't work in the beginning and your eyes pop into your head "Why?" and vice versa, it would seem that the dumbest and most illogical piece of code works for some reason.
a little theory - a little practice

Answer 2

If you get stuck, then stop reading and try to program it.
Skills are the main thing.
