Code::Blocks – introduction
 Code::Blocks: The open source, cross platform, free C, C++ and
Fortran IDE.
 Code::Blocks is a free C, C++ and Fortran IDE built to meet the
most demanding needs of its users.
 Built around a plugin framework, Code::Blocks can be extended
with plugins. Any kind of functionality can be added by
installing/coding a plugin. For instance, compiling and debugging
functionality is already provided by plugins!
 Code::Blocks 13.12 is here! (as of March 2014)
3
Code::Blocks functionality
 Code::Blocks includes:

Code Editor

Compiler

Debugger

Other SW tools
