[Tools] Dev-C++ IDE
If you need to code in C++ without the benefit of Microsoft (C) Visual Studio, but you still want to use an IDE, try the free Dev-C++ IDE by Bloodshed Software. By default, Dev-C++ installs and uses the Mingw port of GCC but it can also be used with Cygwin and other GCC-based compilers.
The Dev-C++ IDE is Free Software (under the GNU General Public License)
