| • | There
are five important stack operations: |
||||||||
| 1) Determine whether the stack is empty |
|||||||||
| 2) Add a new item onto the stack...push |
|||||||||
| 3) Remove an item from the stack...pop |
|||||||||
| 4) Initialize a stack (this operation is
easy to overlook!) |
|||||||||
| 5) Retrieve the item at the top of the
stack...without |
|||||||||
| modifying the
stack...peek |
