      I'm Writing A Program(In C) To Convert Regular
Expressions To DFA's(Directly Without Going Through
Intermediate NFA's) And I'M Following The Procedure
Given In The Dragon Book(Compilers:Principles,
Techniques And Tools). I've Been Able To Handle Cases
For |,.,* Oprators But How Can I Calculate The
Followpos For '?' And '+' Operators? How Should I
Handle These Operators When I Build The Syntax Tree
For A Regular Expression.
