OnlineIDE - Online C Compiler is a web-based tool powered by ACE code editor. This tool can be used to learn, build, run, test your programs. You can open the code from your local and continue to build using this IDE. Borland C Compiler (Free) Borland C is a free C Compiler for Windows. This package has compiler binaries, including libraries, but lacks an IDE, which means you will need to use an editor and shell commands. This compiler is updated with the free Embarcadero C Compiler.

I (Bjarne Stroustrup) am often asked to recommend a C++ compiler. However, I don't make recommendations; that would be too much like taking sides in commercial wars. Also, I don't know every C++ compiler; there are simply too many 'out there'.
I recommend that people take Standard conformance very seriously when considering a compiler. If you can, avoid any compiler that doesn't closely approximate the ISO standard or fails to supply a solid implementation of the standard library. The recent releases from all the major C++ vendors do that.

Most of these compilers are embedded in frameworks of software development tools and libraries. These frameworks, environments, and libraries can be most helpful, but do remember that their use can lock you into a single vendor and that some uses have significant run-time performance implications.
C Compiler Download
When looking for C++ on the web, you find that much of the information is 'hidden' under various product names. In fact, I had more luck finding C++ compilers using google.com than by going directly to vendors that I knew sold them. Here, I have chosen to list C++ implementations simply by the name of their provider, ignoring marketing labels.
Some compilers that can be downloaded for free (do check their conditions/licenses before attempting commercial use):
- Apple C++. Xcode. It also comes with OS X on the developer tools CD.
- Bloodshed Dev-C++. A GCC-based (Mingw) IDE.
- Clang C++. A relatively very active development associated with the analysis and code generation framework, LLVM.
- MINGW - 'Minimalist GNU for Windows'. Another GCC version for Windows including a free (non-GPL) w32api.
- IBM C++ for IBM power, System Z, Bluegene, and Cell.
- Microsoft Visual C++.
- Oracle C++.
Some compilers that require payment (some allow free downloads for trial periods):

- Edison Design Group C++ Front End - used by many C++ compiler suppliers
- Green Hills C++ for many embedded systems platforms
- Intel C++ for Windows, Linux, and some embedded systems.
- Mentor Graphics Sourcery CodeBench An extensive 'Workbench' for many embedded systems platforms.
- Paradigm C++, for x86 embedded systems
- The Portland Group C++ (parallelization and GPUs)
- WindRiver's Diab C++ used in many embedded systems.
It is impossible for me to keep this list complete and up-to-date. The C++ world is just too large and too much new is happening. Apologies to those suppliers who I failed to list, I know there are some, and please, if you have a link that you think ought to be listed here, send me a message: bs at cs dot tamu dot edu. Again: I just list compilers, I don't endorse them. Also, there can be no one compiler that is best for everyone, people's needs differ too much for that. Other lists of C++ compilers:
