C Foundations

A queue as a linked list in C --- contrast with Jill. Elements:

1. Memory: storage, alignment, lvalues, rvalues.

2. Conceptual implementation of this linked list.

3. structs. Self-reference.

4. Overview of queue routines.

5. malloc(), free(), sizeof().

   Re-write test.c to allocate nodes dynamically.

6. Rewrite insqu() and remqu() to take/return key values directly.

   Problems? (Particularly with free'ed memory in remqu(), but also with remqu()'s new user interface.)
