[多选题]So it is today. Schedule disaster,functional misfits,and system bugs all arise because the left hand doesn’t know what the right hand is doing. As work( ),the several teams slowly change the functions, sizes, and speeds of their own programs, and they explicitly or implicitly( )their assumptions about the inputs available and the uses to be made of the outputs. For example, the implementer of a program-overlaying function may run into problems and reduce speed relying on statistics that show how( )this function will arise in application programs. Meanwhile, back at the ranch, his neighbor may be designing a major part of the supervisor so that it critically depends upon the speed of this function. This change in speed itself becomes a major specification change,and it needs to be proclaimed abroad and weighed from a system point of view. How , then , shall teams( )with one another ? In as many ways as possible Informally . Good telephone services and a clear definition of intergroup dependencies will encourage the hundreds of calls upon which common interpretation of written documents depends. Meetings . Regular project meetings, with one team after another giving technical briefings ,are( ). Hundreds of minor misunderstandings get smoked out this way. Workbook . A formal project workbook must be started at the beginning.

正确答案 :D
封装
解析:解析:试题38:封装(enc印sulation)就是将抽象得到的数据和行为(或功能)相结合,形成一个有机的整体,也就是将数据与操作数据的源代码进行有机的结合,形成“类”,其中数据和函数都是类的成员。封装的目的是增强安全性和简化编程,使用者不必了解具体的实现细节,而只要通过外部接口,以种特定的访问权限来使用类的成员。试题39:继承可以使得子类具有父类的各种属性和方法,而不需要再次编写相同的代码。试题40:对象之间进行通信的结构叫做消息。在对象的操作中,当一个消息发送给某个对象时,消息包含接收对象去执行某种操作的信息。发送一条消息至少要包括说明接收消息的对象名、发送给该对象的消息名(即对象名、方法名)。一般还要对参数加以说明,参数可以是认识该消息的对象所知道的变量名,或者是所有对象都知道的全局变量名。
