Code::Blocks is a free development environment for the C++ programming language. It supports 20 different compilers, including Microsoft Visual C++, C Tiny, Digital Mars, and Borland C ++. Plugins galore The program is fully configurable thanks to the numerous plugins and options . Features such as automatic formatting of code or even creating short games in the integrated development environment (IDE) can be accessed at any time by selecting the corresponding extension. Fast build process Code::Blocks gets rid of makefiles , making the build process much faster . If support for parallel compilation was added, the speed with which you can bake your binaries would be tremendous.

If you ever get stuck, just check out the PDF manual .
