Author description: From software's About
-----------------------------------------
Welcome to Code::Blocks 10.05!
Code::Blocks is a full-featured IDE (Integrated Development Environment) aiming to make the individual developer (and the development team) work in a nice programming environment offering everything he/they would ever need from a program of that kind.
Its pluggable architecture allows you, the developer, to add any kind of functionality to the core program, through the use of plugins...
------------------------------------------
Your opinion: Beginner programmers must have. Everyone works on it. I personally recommend it to everyone. It is great. Freeware and opensource, for what can you ask more.
