can anyone suggest me free source code browser (c/c++ )and editor in windows like source insight?

How do I use Source Insight in Windows?

You can just double click on a local or global symbol, and Source Insight takes you to the definition, or can pop up a quick information window. You can click on a symbol, and within seconds, have a list of all references to that symbol anywhere in the project.

Visual Studio Express edition is free...

c/c++ version

It is a full compiler so if you don't need to compile code, it might be a little overkill.
