Is there a tool to ask the computer how it can understand code?

You should learn a bit about C++ before trying to understand C++ code.

Don't those two things go hand in hand?

But it probably would be a good idea to read Bjarne Stroustrup's books.

Yes, I was going to say that too (the hand in hand).
I find, since I restarted doing code recently, that there is so much of everything and everything moves so fast, that it’s best to work with a subset of the thing you are working in, you can always look stuff up anyway and, reversing a habit of a lifetime, it’s a good idea to go in at the highest level you can. I tended to just naturally code in C++, but now I discovered Python.

I take the following line in stockfish's code that is the first line in main.cpp line 37

Code: Select all

std::cout << engine_info() << std::endl;

Do you want to find where the implementation of "engine_info()" can be found, or do you want to figure out what std::cout is doing?

For std::cout, just look here:
https://en.cppreference.com/w/

The search function brings you to here:
https://en.cppreference.com/w/cpp/io/cout

std::cout and the << operator are just unnecessarily "cute" ways to print stuff.
