What are the standard C++ libraries and is there a chart of them with descriptions of what they let us do?

Question

In the C++ lessons we learn about some "standard libraries" C++ has. We include them in our source code.

Where do these library files exist? What is the structure where these files are placed called? Is there a resource that lets us know what the standard libraries let us do?

Ever since I learnt about C++ this part of it seems to never be explained, lessons are always focused on the coding aspect but there is always little said about what's "under the hood" of C++.

Answer 1

The official documentation is your best friend.

As for where these files exist, they are specific to the platform. Linux/Unix-based systems, for example: /usr/local/include. For Windows, the headers do not come preinstalled, but rather with a compiler, so the exact location depends on where the compiler is installed on the filesystem.
