Question

Well I have been wondering if there is a standard socket header file for C++

I did search the whole internet (using google search engine ), but couldn’t find any standard socket header file for C++ , beside finding some libraries, like Boost, chilkat etc…

I have only succeeded in finding a standard socket header file for C programming language.
If I used the C standard socket header file, but inside my C++ code, does it mean my program
is Pure C++ or C and C++?

Because I didn’t find any standard C++ socket header file. Like
there is <string> for C++ and there is <string.h> for C, but there is no socket
standard header file for C++.

I hope someone C/C++ wise would explain all that for me, step by step.

Answer 1

There is no standard socket library in C++. You can either use whatever sockets API your operating system provides (typically a C API, on Unix operating systems it would be the BSD sockets API), or you can use a C++ library like Boost.ASIO, which is cross-platform.
