Does end() point to the last item?
Short answer. No. One past the last.
What does push_back do?
Adds at the end.
Remember
| vector grows by itself |
| end() is past the last |
Arrays are fixed. Need one that grows? The vector holds seven and nine. Push back adds four. End points one past the last item. So end minus one gives four. Remember two things. A vector grows by itself. End is one past the last.
