Array

Hi,

Recently,I have used bison to do somthing on Lexical
Analyzer & Syntax 
Analyzer.

I checked the bison manual and found there only examples of
yyin is ostream 
type and FILE * type, does the yyin support the variable
type ? I 
recomplied the example of rpcalc in bison manual ,if I
define a const 
variable with char * type in main(void) and want to make the
yyparse() 
parse it correctly, what & how should I do ?

I am looking forward to your reply and appreciated for it!

Best Regards,
Wang Yige

The Bison generated parsers parses a stream of tokens. It is
the  
lexers that feed the parsers that make use of character
streams. If  
you use Flex to generate your lexer, you might try: Flex
Help <help- 
flexgnu.org>.
