	1. Stack		stack

Supplied by: Brian Takita <e-mail contact>

A stack (LIFO) data structure.

The Stack class advantage over the array_push and array_pop function is Stack::pop() pops the stack and returns a reference to the popped element. There is also a top function that returns a reference to the top element.

	2. Screen Stack		stack

Supplied by: Wolter Kaper <e-mail contact>

Implement stacked pages navigation

Some sites that implement screen oriented tasks consist of a set of pages organized in the form of a tree hierarchy.

For instance, the user starts at screen A which has some buttons that may open screens B or C. When the screen B is opened, the associated task has to be completed or canceled before the user is allowed to return to screen A. Screen B in itself can also have buttons that open screens D and E, and so on.

In each situation, a stack describes the structure of screens that have to be completed. This class can be used to implement stacks of screens that define the navigation of pages that the users of a Web application must follow. The stack is defined by the URLs of the pages.

	3. Polymorphic Queue		stack

Supplied by: Carlos Blanco Domínguez <e-mail contact>

Implement a LIFO queue with arrays

This is a simple class that implements a FIFO stack (First In First Out) of values.

It uses arrays to queue values of any type at the end of the queue.

The class can also pop values from the stack by the same order they were queued. It may also return the value at the head of the queue without removing it.

Implement a LIFO stack with arrays

This is a simple class that implements a LIFO stack (Last In First Out) of values.
