Which ones are the most frecuently used standard and no standard libraries (besides iostream and string) in a C++ program? Where can I get some good language reference info with examples that gets deeper on this?

Question

I know that this is a introductory course to C++, but it should include some lessons about what you can do with the standard libraries, the most common used (besides iostream) and where to get information on this topic... what do you think?

Answer 1

Boost is a non-standard library that finds its way into almost all C++ software. Many of the changes in of the standard library in the newer standards as C++11 and 14 wer first conceived in the Boost libraries and then later slightly modified and put into the standard library.

Answer 2

#include <cstdlib>
