Static Typing - Type of variables must be declared at compile time (e.g. C++) Dynamic Typing - Type of variables determined from usage at runtime (e.g. JavaScript) Strong Typing - Variables cannot be coerced to unrelated types. (e.g. Java) Weak Typing - Variables can be coerced to unrelated types. (e.g. C) These are the definitions I've seen in writings from academia over the past few years. -----Original Message----- From: Sean McGrath [mailto:sean.mcgrath@p...] Sent: Wednesday, February 12, 2003 12:37 PM To: Dare Obasanjo; xml-dev@l... Subject: RE: Strong versus (weak|runtime) typing Dare, I'm intrigued. How would you define "weak typing"?
