Thread: What should I study next?

Hello.

I'm a 39 year old man from the northwest of England, self-trained in computer programming. I'm trying to learn C++.

So far, I've read the first 3 chapters of "A Tour of C++". I'm understanding everything, but I regret that there are no exercises for me to do - I have to invent my own. I have watched some CPPCon videos, but a lot of them goes over my head.

I wonder what I should study next. Reading more of "Tour" doesn't feel right.

For the record, this is what I have read so far this year:
