The cplusplus.com tutorial only covers the syntax of C++, but doesn't go into anything practical, such as working with more than one source file, or how header files work, or how to compile a program that has multiple files. The tutorial at learncpp.com though covers all of these things and then some -- it even explains how C++ programs are organized and a bunch of other helpful techniques that clears up a lot of the fuzziness that other tutorials leave ya with.
So after a week and change, I've gotten about halfway through the tutorials and am attempting to write my own programs from scratch -- actual programs, not tutorial-like things. So, I've decided to start piecing together a CyanChat library. Why CyanChat? Because of its simplicity:
Programming this CyanChat library so far is a bit more tricky than it was in Perl and Java. There is a full C++ CyanChat client available named Magenta, but looking at its source code doesn't help me very much -- this is a Windows application, and the source file that handles the sockets is an override of the Win32 CSocket library, which is Windows-specific. I want to use something cross-platform.
Right now I'm using the rudesocket C++ library, although I may need to ditch it for something different, because its setTimeout() function doesn't seem to work and so reading from the socket hangs until the server sends data. This isn't scalable.
When I get the library completed, I'll try building it on Windows to get that experience (that'll be a blast...), and then I'll attempt to build a dynamic Windows DLL file from it -- and then link that DLL into Perl using Win32::API -- to see that everything is successful.
My eventual goal in C++ programming is to build a RiveScript interpreter library in it, and build it as a dynamic DLL, so that practically every programming language will then be able to link it and use it (or C/C++ programs can statically link it from its source code if they want). I could even create a Perl module named RiveScript::XS, which compiles statically with the C++ RiveScript interpreter, which might give it additional speed over the pure-Perl RiveScript module -- or again, just to see that it all works how I want it to.
