22:00 One doubt. Should we consider negative numbers also? ie -123.45 -123.45 E 67 And all Instead of digit+ (.digit+)? (e[+-]? digit+)? . . [+-]? digit+ (.digit+)? (e[+-]? digit+)? I think the second one could only represent all real nos Please correct me if I am wrong.

Sir what are the problems that arise during token recognition?

[@SudhakarAtchala]

issues of tokenization are language-specific. It thus requires the language of the document to be known. Language identification based on classifiers that use short character subsequences as features is highly effective; most languages have distinctive signature patterns.

[@SudhakarAtchala]

In c language for is a keyword where as in cobol for is not a keyword.
