4.1 Stacks and queues
New Words & Expressions:
stack n. 栈，堆栈 attribute n. 属性，性质 overflow n. 上溢
栈和队列都是动态的集合，其中的元素由预先定义的删除操作可将其去 除。在栈中，最近被插入的元素最先被删除，即栈是按后进先出(LIFO) 的原则进行的；类似的，在队列里，被删除的元素是最早进入队列的， 即队列是以先进先出(FIFO)的原则进行的。在计算机上，对于栈和队列 有几种有效的实现方法，这一节我们给出如何用简单的数组来实现它们。

4.1 Stacks and queues
4.1.2 Queues
We call the INSERT operation on a queue ENQUEUE, and we call the DELETE operation DEQUEUE; like the stack operation POP, DEQUEUE takes no element argument. The FIFO property of a queue causes it to operate like a line of people in the registrar's office. The queue has a head and a tail. When an element is enqueued, it takes its place at the tail of the queue, just as a newly arriving student takes a place at the end of the line. The element dequeued is always the one at the head of the queue, like the student at the head of the line who has waited the longest. (Fortunately, we don't have to worry about computational elements cutting into line.)

Unit Four Software Engineering 软件过程Text A Software processes软件过程A software process is a set of activities that leads to the production of a software product.一个软件过程是一组引发软件产品生产的活动。

These activities may involve the development of software from scratch in a standard programming language like Java or C.这些活动刻画了软件使用像Java或C这样的标准编程语言从头开始的一步步的开发过程。

Increasingly, however,new software is developed by extending and modifying existing systems and by configuring and integrating off-the-shelf software or system components.然而，现在越来越多的软件是通过在旧软件基础上修改或通过配置和集成现成软件或系统组件而形成。

Software processes are complex and, like all intellectual and creative processes, rely on people making decisions and judgements.软件过程是复杂的，像所有智力过程一样，它依赖于人的判断。

Because of the need for judgement and creativity, attempts to automate software processes have met with limited success.因而需要判断和创造力，软件过程自动化的尝试只获得了有限的成功。
