I'm sure *everybody* would like to hear about any purported C implementations
that work the way he states, because they wouldn't be C implementations.
"foo[]" is an array of characters, and as such in *any* valid C implementation
"sizeof foo" will return the number of "char"s the array takes up, namely 16.
