A programming language intended to be a successor to C. Provided access to a variety of extended programming constructs such as templates, classes, methods, etc.
The official title is ISO/IEC 14882. The latest revision is "C++ 03", aka ISO/IEC 14882:2003. It updates the original 1998 edition with some errata. The specification can be downloaded in PDF form from ISO for 352 CHF. The very same PDF document (but for the title page) can be downloaded from ANSI [L1 ] for a mere US$ 18. You can also download it for Free from Google Code: [L2 ].

DKF: Tcl is not written in C++, but rather in C. This is not about to change, as it remains relatively difficult to do extremely portable ABIs in C++ due to the exact details of how compilers convert source code into object code; the tendency with C++ is to spread implementation details across class boundaries at the ABI level, which is a bit faster but also far more entangling. As such, Tcl sticks with C (and in fact a very codified and restricted type of C at that); in engineering terms, we're very conservative.
What we would like to be able to do, but can't at the moment, is unequivocally recommend a library for people who do want to mix modern Tcl and modern C++…
"Making C++ Loadable Modules Work "
A helpful guide to problems that can arise when writing Tcl extensions in C++. Written in 1998, so its documentation on the limitations of some compilers may be out of date.
Work is under way for an update of C++, codenamed "C++ 0x" (so the ISO/IEC working group seems to have some hope of finishing within this decade). Extensions that are being considered include
This was completed in 2011.
willdye If you're searching for references to C++, then you might want to also search for strings such as "cpp" or "cplusplus". The "++" characters are problematic in certain situations, so the name "C++" has many synonyms.
underC [L3 ] an interesting lightweight C++ interpreter. The author implies [L4 ] that it should be easy to interact with Tcl/Tk from it.

Marco Maggi quips: C++ is "the tool of the angels: only in heaven you have infinite amount of time to devote to design analysis (and to wait for the compiler to finish)."
dkf on the chat: "C++ doesn't just provide you with enough rope to hang yourself. It also provides a do-it-yourself scaffold (with instructions translated from Klingon by Papuan tribesmen). ... Experts can do very cool stuff with C++. Utter dummies can do cool stuff with C++. But everyone else is in trouble..."
