The goal of this book is to introduce you to the C programming language. Basic computer literacy is assumed, but no special knowledge is needed.
Popular C compilers Include:
|Microsoft Visual Studio Express||Visual Studio||Windows||Free Version||Powerful and student-friendly version of an industry standard compiler.|
|Tiny C Compiler (TCC)||tinycc||GNU/Linux, Windows||LGPL||Small, fast and simple compiler.|
|Clang||clang||GNU/Linux, Windows, Unix, OS X||University of Illinois/NCSA License||A front-end which compiles (Objective) C/C++ using a LLVM backend.|
|GNU C Compiler||gcc||GNU/Linux, MinGW(Windows), Unix, OS X.||GPL||The De facto standard. Ships with most Unix systems.|
The minimum software requirements to program in C is a text editor, as opposed to a word processor. A plain text Notepad Editor can be used but it does not offer any advanced capabilities such as code completion or debugging. There are many text editors (see List of Text Editors), among the most popular are Notepad++ for Windows, Sublime Text, Vim and Emacs are also available cross-platform. These text editors come with syntax highlighting and line numbers, which makes code easier to read at a glance, and to spot syntax errors.
Though not absolutely needed, many programmers prefer and recommend using an Integrated development environment (IDE) instead of a text editor. An IDE is a suite of programs that developers need, combined into one convenient package, usually with a graphical user interface. These programs include a text editor, linker, project management and sometimes bundled with a compiler. They also typically include a debugger, a tool that will preserve your C source code after compilation and enable you to do such things as step through it manually, or alter data as an aid to finding and correcting programming errors.
For beginners it is recommended not to use an IDE, since it hides most of what is going on. Using the command line builds up familiarity with the toolchain. An IDE may be useful to somebody with programming experience but knows how the IDE works. So as a general guideline: Do not use an IDE unless you know what the IDE does!
Popular IDEs Include:
|Eclipse CDT||Eclipse||Windows, Mac OS X, Linux||Open source||Eclipse IDE for C/C++ developement, a popular open source IDE.|
|Netbeans||Netbeans||Cross-platform||CDDL and GPL 2.0||A Good comparable matured IDE to Eclipse.|
|Anjuta||Anjuta||Linux||GPL||A GTK+2 IDE for the GNOME desktop environment.|
|Geany||geany||Cross-platform||GPL||A lightweight cross-platform GTK+ notepad based on Scintilla, with basic IDE features.|
|Little C Compiler (LCC)||lcc||Windows||Free for non-commercial use||Small open source compiler.|
|Xcode||Xcode||Mac OS X||Free||Available for free at Mac App Store.|
|Pelles C||Pelles C||Windows, Pocket PC||Free||A complete C development kit for Windows.|
|Dev C++||Dev C++||Windows||GPL||Updated version of the formerly popular Bloodshed Dev-C++.|
|Microsoft Visual Studio Express||Visual C++||Windows||Free||A powerful, user friendly version of an industry standard compiler.|
|CodeLite||CodeLite||Cross-platform||GPL 2||Free IDE for C/C++ development.|
|Code::Blocks||Code::Blocks||Cross-platform||GPL 3.0||Built to meet users' most demanding needs. Very extensible and fully configurable.|
On GNU/Linux, GCC is almost always included automatically.
On Microsoft Windows, Dev-C++ is recommended for beginners because it is easy to use, free, and simple to install. However, the official release of Dev-C++ hasn't been updated since 22 February 2005. An unofficial version of Dev-C++ is being actively developed however. An alternate option for those working only in the Windows environment is the official Microsoft Visual Studio Express which is free and has an excellent debugger.
On Mac OS X, the Xcode IDE provides the compilers needed to compile various source files. The newer versions do not not include the command line tools. They need to be downloaded via Xcode->Preferences->Downloads.
- Actually, GCC's(GNU C Compiler) cc (C Compiler) translates the input .c file to the target cpu's assembly, output is written to an .s file. Then as (assembler) generates a machine code file from the .s file. Pre-processing is done by another sub-program cpp (C PreProcessor), which is not to be confused with c++ the compiler.
