Where can I find interesting tasks for learning C++?

Question

Programming

Good evening. I'm learning C++ from Dawson's book. There are practical tasks there, but I still lack them. I would like after each new topic (data types, branching, strings) to solve 10-20 tasks to consolidate the material, and not trivial ones, like displaying the day of the week by its number, etc., but something interesting where you need to think about the algorithm . Is there such a resource/book?

Answer 2

Q :
I'm learning to read alphabetically. There are practical exercises, but not enough. I would like to read 2-3 books after each new letter ("o", "p", "r") to consolidate the material, and not trivial ones, like "mom washed the frame", but something interesting, like the three musketeers. Is there such a resource?
A :
No.
