Not a requirement, but a definition.  Section 7.1.1 of the ANSI C
standard says

	A string is a contiguous sequence of characters terminated by
	and including the first null character.

This is merely a small confusion of terminology, though.  An Ada string
is simply an array of characters (of a particular type).  It is important
to remember that a C array of characters (char[]) may or may not contain
a "string"; a C pointer to [array of] character (char*) may or may not
point to a "string".
