(You can't control if some alien compiler puts out weird warnings because it used MS-Word to grammar-check your comments.) Also, watch your warnings like a hawk, and don't release code that emits any warnings in your chosen build environment(s). Of course, only silence this warning when the code really is doing what you intend, and please put a comment nearby to testify to this fact and explain why. In my opinion, the extra parentheses highlight the fact that this expression isn't Business As Usual, so the reader will look at it more carefully and is more likely to notice that it uses assignment instead of comparison. X = 5 /* Nothing happens, except maybe a warning if -Wall is on. This is very easy to confuse with the comparison operator =, resulting in either of the following two coding errors: (x86 only as of Jun 2003)ĪMG: One annoying thing about C is that, like Fortran, it uses = as its assignment operator. In milliseconds for a small chunk of code. Tcc provides a libtcc library, which allows a running program to compile and link C code without touching disk. Support for C can also take the form of a run-time compiler. In Jan, 2003, the product page for Ch Standard says that the product is free for use on Unix, Linux, and Mac OS X. It supports 1990 ISO C standard as well as C99 features. It provides not only standard language features, but also support for 2 and 3 dimensional plotting, shell programming, and numerical programming. I do not know if Tcl can be interpreted under this interpreter Ch a C/ C++ interpreter that runs cross-platform on a large number of operating systems and hardware. Historical Macintosh Programmer's Workshop : for MacOS Classic Abandonware Interpreters CInt RFox: a (free) interpreter, originally from Masaharu Goto, and apparently currently maintained by the CERN Root team which uses CInt as its scripting language. Now only avaialable as a component of Visual Studio. For AIX, IBM i, Blue Gene, Linux, z/VM, Z/OS Intel C++ compiler : Commercial LCC-Win32 Commercial. Was once Zortech C and later became Symantec C IBM XL C and C++ Commercial. Versions for Windows and MacOS Classic and MacOS X previously existed. An older command-line version is still available as a free download freescale CodeWarrior Commercial. Proprietary Compilers C++Builder Commercial. Companion to Practical Compiler Construction: A Non-nonsense Tour Through a C Compiler. It can compile itself and passes gcc -Wall -pedantic. A fast and simple public domain compiler for a clean subset of the C programming language. clang C language family frontend for LLVM Cygwin C compiler (free a version of gcc for some strange reason it cannot be used to compile the Tcl source code out-of-the-box - but Cygwin comes with its own version of Tcl at least), Mingw C compiler (free another version of gcc for Windows with goals slightly different from Cygwin), OpenWatcom C/C++ compiler Free. Apple XCode provides a gcc distribution for Mac OS X. Dialects Cyclone a safe dialect of C Free Compilers gcc, by the FSF a quite popular C compiler found on many platforms and operating systems. They are often unbundled products these days. Most Unix systems provide vendor-supported compilers. Some efforst at a C interpreter also exist. Support for C is traditionally provided by a compiler. The ANSI committee as well as the ISO committee have approved a standard reference for C.
