The empty string is an expression. Therefore "sizeof (int)" is the empty expression cast to type "integer" and an expression. Therefore "sizeof (int)" is of the form sizeof <expression> .

I bet Ritchie would be surprised to learn that.

Yeah, then it's obviously a bug that my compiler won't let me do a = (int); According to the K&R: Statement = ; expr ; ... list of things like while, if etc... Expression = primary unary expression ...list of things, non of which are null... unary-expression: ... all the others... (type-name) expression sizeof expression sizeof (type-name) -Ron

Therefore > "sizeof (int)" is of the form sizeof <expression> . sizeof (int) "" would be sizeof <expression> Whitespace is not equivalent to the empty string. I'd sure hate for a = *b; to be interpreted as a = ""*b; -- Norman Diamond UUCP: {decvax|utzoo|ihnp4|allegra}!watmath!watdaisy!ndiamond CSNET: ndiamond%watdaisy@waterloo.csnet ARPA: ndiamond%watdaisy%waterloo.csnet@csnet-relay.arpa "Opinions are those of the keyboard, and do not reflect on me or higher-ups."
