i finished exercies(rewinding yyin, closing and opeing the yyin, and
calling yyrestart before the second call) what u said, At the first call
the output is looks like below one.


--(end of buffer or a NUL) ----->(First call of yyparse)
--accepting rule at line 60 ("<?EML-VERSION 1.0?>")
--accepting rule at line 69 ("
<?ETT")
--accepting rule at line 59 (" ")

goes on......



--(end of buffer or a NUL)
yywrap called
--EOF (start condition 1)
Test-1: parser passed    ---> (First call is finished)
--(end of buffer or a NUL)  ---->(Second call of yyparse)
--accepting rule at line 75 ("<")
Got an Error
!ERROR(<)
--accepting rule at line 74 ("?EML-VERSION 1.0?>")
Syntax error: parse error
Test-2: parser failed
Press any key to continue
