i used the istringstream and it works the speed performance is much better now and getting close to ANAGRAM. thank you for that. however when trying to work with the flex lexer, i took the LexTokenStream.cpp and lexTokenStream.hpp,added them to my project. upon linking i got the following messages: LexTokenStream.obj : error LNK2001: unresolved external symbol _yyrestart LexTokenStream.obj : error LNK2001: unresolved external symbol _yytext LexTokenStream.obj : error LNK2001: unresolved external symbol _yylex my question is where can i find definitions for that symbols or should i define them myself. sincerely merom klein    More>>

the speed performance is much better
now and getting close to ANAGRAM.
thank you for that.

however when trying to work with the flex lexer, i took the LexTokenStream.cpp and lexTokenStream.hpp,added them to my
project. upon linking i got the following messages:
LexTokenStream.obj : error LNK2001: unresolved external symbol _yyrestart
LexTokenStream.obj : error LNK2001: unresolved external symbol _yytext
LexTokenStream.obj : error LNK2001: unresolved external symbol _yylex
my question is where can i find
definitions for that symbols or should
i define them myself.

I'm not 100% sure... been awhile since I used flex. Wasn't there a
libflex library? libfl maybe? A bit of
RTFM might help =)
