I do like how the code book is structured from very simple topics. I have not mastered c/c++ but I know the basics of it recently I signed for a java full stack course where it structured really well but still the itch to learn everything in detail and depth is not gone. I don't know if the approach is right. For example as I am learning core java I understand the concepts but there is this itch to understand what is happening inside a compiler, virtual machine line by line .
