Ubuntu+gedit+terminal is all time best …
Can’t Compare Visual Studio with any of the IDE’s, but to mention, Vim is the worst editor I have ever used, Icannot just understand what it needs to get prepared for writing a code! Hrrible Interface , like I am using a Windows 95 PC.
I use the Dev-C++ for CPP codes. Great interface, good code completion. Terrific!
I use “Geany” for all coding related stuff, and I love it.(I’m on Ubuntu)
I’ll give it a chance, this “multi editing” feature looks fine 
I have been using this for quite some time. Just love it. Superb editor.
Good one for online code judging. I use this quite a lot too. But my preference is, write code in some editor in my system (I use Sublime Text 2), and then compile and run it online.
I agree… It is a matter of taste. I was also looking for some IDE (editor + compiler + linker + whatever the need be). But ever since I started using Sublime, I am happy with sublime + ideone.com 
(Occasionally, I use the terminal as well, for compilation and execution).
As a fanboy :P, I use Visual Studio for everything (C++, C# and Python).
Fantastic editor 
After reading this i downloaded sublime . But i am unable to compile and run program using sublime.Do i need to compile using cmd?? plz help…
i have already installed gcc compiler.
@abhi : You can either use terminal or use the way suggested here http://discuss.codechef.com/questions/15926/how-to-compile-and-run-cc-code-from-sublime-text-2-editor/16067
+1 Vim is really a life saver. It supports code completion too!
Surely Sublime is the best
