bison / flex
i was using flex to print to a file fie1.txt after scanning through a file file0.txt
i was using yyin = fopen(file0.txt,r);
yyout = fopen(file1.txt,w);
now i am using bison and returning fromm flex file in place of printing,
what should i use in place of yyin and yyout in bison .y file .
and what i have to take if i need to open two files for writing file1.txt and file2.txt.
i think i cant use yyout1 and yyout2
