Actually, he might well know C. 

	char c = ''; 

doesn't compile with GCC 4.4.4 or with my ancient copy of the K&R C that
was supplied with Microware's OS-9/68K v2.4. I thought it was unlikely
to be strictly legal C and wasn't sure whether some compilers would
accept it, so ran a couple of tests earlier today. Other compilers may
accept it but those are the two I have immediately available.

On the face of it, a compiler should throw an error since, unlike
"" (the empty string) char is a fixed size variable, which makes
supplying an empty literal a meaningless expression.
