The addition and deletion of elements in a stack can only occur at the top of the stack. This is because a stack follows the Last-In-First-Out (LIFO) principle, where the last element added to the stack must be the first one to be removed. Therefore, elements cannot be added or deleted from the middle, bottom or head of the stack.
