States and Invariants

• State: A state describes discrete change in the activity of a system on the physical electrical or the quantum level or the virtual level.
• Invariant: A predicate (or property) that is perserved for each state across the states chain under all state transitions; that is P(v) is true for all the members of the set of labeled arcs or in Automata Theory the set of delta functions $$\Delta$$ representing the state transitions in an Automaton.

Here is an example of a non-null terminated list:

#include <stdio.h>
#include <stddef.h>

typedef struct buffer (buffer);

struct buffer {
    void *start_address;
 void *end_address;
