Hi, is there anyone who knows whether the output of Yacc and Lex program (C) can be compatiable with C++ programs? Or, is there any C++ version of Yacc/Lex where the user-defined functions can be C++ programs? Thanks a lot. yms@beach.cis.ufl.edu

You could just experiment with yacc and find out if it works. I was doing
just that the other day, and it seems to work fine, all I needed was a few
function prototypes, which I was able to add in the initial definitions
section. Something like:
%{
extern int yyparse();
%}
I used g++ and my test parser built and ran fine after that.
I seem to recall hearing vague reports of something called yacc++, but I
don't know exactly what features it might provide especially oriented
towards C++.

A related note: There is a tool called `mkproto' which could automatically generate function prototypes for classic C. This was posted on comp.sources.misc (or was it comp.lang.c?) sometime back. -- S Manoharan Internet : sam%ed.lfcs@nsfnet-relay.ac.uk Dept of Computer Science Uucp : ..!mcsun!ukc!edcastle!sam University of Edinburgh Fax : 031-667 7209 Edinburgh EH9 3JZ UK.
