That's ingenious.

Thats crazy.. In yet i wonder if it's possible to make a C++ command line? LOLS

EDIT
err.. console, rather.

@Chris, That's cheating, IMO :P

Though it would be interesting to design a C++ interpreter that's completely compliant with the current standard.

Well, Beanshell (http://www.beanshell.org/) is a Java interpreter, so I suppose it's possible.

I would expect creating an interpreter for a language that already runs on a virtual machine would be easier than one that's compiled to native code.
chrisname (7395)
I don't see why.

chrisname -- heh, that would be interesting creating a full fledged C++ shell, with dynamic library loading.. probably pointless though :D

Well, there's CINT...

http://root.cern.ch/drupal/content/cint

CINT is an interpreter for C and C++ code. It is useful e.g. for situations where rapid development is more important than execution time


CINT covers most of ANSI C (mostly before C99) and ISO C++ 2003.
