Preface: s is a struct pointer, items[ ] is a member array, and top is
a member int.
void push(Stack *s, int i) { s -> items[s -> top++] = i; }
ORDER Operator
1st left most -> comment: Postfix ++ is lower
than =
2nd [ ] but this one
executes before =
3rd 2nd -> because it's
inside [ ].
4th Postfix ++
5th =
int pop(Stack *s) { return s -> items[--s -> top]; }
ORDER Operator
1st left most -> comment: All the operators
in pop( )
2nd [ ] are Level 1.
Prefix -- executes
3rd Prefix -- before the 2nd -
itself gets decrimented?
If so, would that cause s to no longer point at the struct
instance?
