[h-e-w] c++ editing , variable name completion

[john ware]

Hi,
   Is there a mode which will perform variable name and function name 
completion for C++.

   By this I mean, if you type in the the beginning of a variable name 
and hit the proper key combination then a list of all possible symbols 
which are valid in the scope are displayed. I know that the JDEE mode 
will do this for java code, but alas, I am back working with C++.

thanks,

john ware
