1. Target Audience
Welcome to Learning GNU C. The aim of
this book is to teach GNU users how to write software in C. It is
written primarily as a tutorial for beginners but should be thorough
enough to be used as a reference by experience programmers. The
basics are layed down in full in the first few chapters, beginners
will read these chapters carefully while those with prior experience
can skim through them. All the information is there, no prior
knowledge of programming is assumed.
The reader is assumed to have access to a computer with a GNU
system installed. Although the target audience is GNU users, the
content of the book should also be 98% relevant to users of OpenBSD,
FreeBSD, or NetBSD. Some familiarity with using your computer from
the shell (the command line) would be helpful although all commands
will be shown along side programming examples. The only piece of
software you do need experience with is a text editor. Any text
editor will do. GNU Emacs is an especially good one for programmers.
It has been in development for over twenty years and contains hundreds
useful features. GNU Nano is a simple text editor you could use, some
programmers like to use vi (pronounced vee eye). If you already have
a favorite text editor, you can use that. There are also graphical
editors geared towards programmers such as Anjuta and KDevelop but
most programmers preferr text based editors.
