Is there a website like Hackerank that has multi-threading problems in C++

I am trying to learn all I can about multi threading in C++, but reading and watching videos only go so far. I need problems, but where can I find those problems?

See this:

https://www.tutorialcup.com/cplusplus/multithreading.htm
http://www.tutorialspoint.com/cplusplus/cpp_multithreading

The latter actually a bit dated. Better use std::thread instead of pthread_...(). See:

http://www.cplusplus.com/reference/thread/thread/
http://www.cplusplus.com/reference/multithreading/

The most important thing to konw about threads is to protect the variables that are shared across two or more threads. Apart from this there is not much more secrets behind it.

But they don't have any problems? Thanks for effort though.

What about creating a producer-consumer type app?
One thread could read a large file in junks and the other thread performs some operation on the data and writes it to a file.
