    The basic problem with passing arrays as values in C is that in
general you don't know how big the array is.  Consider:

	int a[20];		/* here you know */
	extern int b[];		/* no telling */
	    int c[];		/* can't tell */

    Pascal treats the length of an array as part of its type.  However,
this is everybody's least favorite feature of the language, since it
makes general array-handling subroutines impossible to write.
    The length of a structure is determinable from its declaration, so this
problem doesn't arise for structures.
