Dear Reders,
Please clear my following doubts regarding the YY_FLUSH_BUFFER. The program and its output is given below..........
Generally YY_FLUSH_BUFFER
flushes out all the content of yytext. But from the following program I
understood that it flushes only first two letters from the first
token.............
If you can spare some time clear this doubts it would be very helpful for me.....................
Thanks
truly
