These are questions about C++ Style and Technique that people ask me often. If you have better questions or comments on the answers, feel free to email me (bs@research.att.com). Please remember that I can’t spend all of my time improving my homepages.

The definitions/explanations of individual terms are necessarily very brief. To compensate, each entry includes one or more references to The C++ Programming language (Special Edition) (TC++PL) where you can find more comprehensive explanations and code examples. I use section references, rather than page numbers, so that this glossary can be used together with translations of [...]
This file should enable the reader to examine running ObjC-Programs using GNU Objective-C and gdb on non-NeXT-Machines. The examples are tested with gcc-2.6.3 and gdb-4.13.
Suggestions are welcome.

Objective-C is a powerful, easy-to-learn, object-oriented extension to C. Unlike in C++, advanced object-oriented features like dynamic binding, run-time type identification, and persistence are standard features in Objective-C which apply universally and work well together. Moreover, the support for descriptive message names (a la SmallTalk) makes Objective-C code easy to read and understand. Objective-C is [...]
Object-oriented programming, like most interesting new developments, builds on some old ideas, extends them, and puts them together in novel ways. The result is many-faceted and a clear step forward for the art of programming. An object-oriented approach makes programs more intuitive to design, faster to develop, more amenable to modifications, and easier to understand. [...]
void assert(int expression);
Macro used for internal error detection. (Ignored if NDEBUG is defined where <assert.h> is included.) If expression equals zero, message printed on stderr and abort called to terminate execution. Source filename and line number in message are from preprocessor macros __FILE__ and __LINE__.

One of the problems with developed programs, is that they tend to grow larger and larger, bringing up overall compilation and linking time to a large figure, and polluting out makefile, and the directory where we placed the source files. The first time a program we write reaches this state, is normally when we look [...]
This document tries to give the reader basic knowledge in compiling C and C++ programs on a Unix system. If you’ve no knowledge as to how to compile C programs under Unix (for instance, you did that until now on other operating systems), you’d better read this tutorial first, and then write a few programs [...]
In order to use Solaris and most other Unix Systems you will need to be familiar with the Common Desktop Environment (CDE). Before embarking on learning C with briefly introduce the main features of the CDE.

This document has evolved over time and contains a number of the best ways to hand-optimise your C-code. Compilers are good, but they can’t do everything, and here I hope to help you squeeze the best performance out of your code. This is not intended for beginners, but for more experienced programmers.
