CodeBlocks is an open-source, cross-platform (Windows, Linux, Mac OS), and free C/C++ IDE. It supports many compilers, such as GNU GCC (MinGW and Cygwin) and MS Visual C++. It supports interactive debugging (via GNU GDB or MS CDB). Code Blocks is surprisingly versatile, and in my opinion, much better than the Visual Studio suite.
