Lines: 61 Xref: watmath net.lang.c:3846 net.unix:3295 net.lang.st80:148 Last December or so, I asked for information on C++. The following is a summary of the responses. C++ is essentially standard C with an additional data type of 'class'. Classes contain private and public parts which can be either variables or functions. There are also ways for classes to inherit a parent classes variables and functions, and for classes to share these elements. ( This is a very rough overview, and doesn't really say enough, but I'll give references to other sources ) C++ is developed at our good friends AT&T Bell Labs. It is currently out, but is available to educational institutions only. There are many runors flying around that it will never really become a product, but that seems to be up to AT&T marketing. There is a paper by Bjarne Stroustrup in the October 84 issue of the Bell Labs Tecnical Journal. A C++ reference manual is reportedly available from Bell Labs. I don't have one, and haven't seen any address more specific than AT&T Bell Laboratories, Murray Hill, NJ 07974. I'm not sure about this, but the manual may be available only to educational institutions also. Also from AT&T Computing Science Technical Report No. 108 and 109 respecively The C++ Programming Language - Reference Manual Data Abstraction in C That's about it for C++, AT&T itself seems to be rather closed mouth on the subject. Most (if not all) of the responses I got were from outside AT&T. There's one other product Objective-C that's available from Productivity Products International, 27 Glen Road, Sandy Hook, CT 06482 ph (203)426-1875. It's a pre-processor and a library which add some smalltalkish extensions to the C language. The price depends on the number of users (size of the machine) and starts at something like $5000. There may be other object oriented Cs out there, but these are the ones I've heard of most. Thanks to all those who responded to my query.
