C++ interpreter / console / snippet compiler

Question

I am looking for a program where I can enter a C++ code snippet in one window, press a button, and get output in another window. Compilation should somehow be hidden behind the button. On a per-snippet basis would be fine, full interactive probably asking too much. It should run under Linux/Unix. Main use case would be learning/testing/short debugging, etc.

Related stuff I found:

-- the Reinteract project for python (which i'm told sage has features similar to)

-- the same thread for C# here: C# Console?

-- the CINT interpreter from the CERN ROOT project (which may be close, but maybe there are more comfortable apps around)

-- some programs called Quickly Compile or Code Snippet, which are M$.

Answer 1

http://codepad.org/ works nicely for this purpose. By default, it will run what you paste when you hit submit and display the result (or any errors you might have).

Answer 2

Dinkumware has a page for this AND you can choose the compiler

Do something like this ? test a C# snippet code by just copying it to the clipboard and then type csc.exe: http://reboltutorial.com/blog/redirect-shell-to-rebol-console/
