图书管理系统可以方便图书销售过程中的各个环节，有利于图书类企业流动资金加快，有利于企业成本降低，更有利于他们即使掌握各种销售与库存信息，然而现在大多数的系统设计时都没有考虑到将来的需要，设计接口不够灵活，以至于当前环境变化后不能很好的适应新环境，造成软件寿命的简短，要想实现软件寿命的延长，就必须在设计软件的全过程中灌入一种动态的有预见性的设计，只要这样，将来条件发生了改变，软件只需局部做一些调整就能够适应新环境。(Library management system can easily book all aspects of the sales process, help speed up books like corporate liquidity, help enterprises to reduce the cost, even if they are more conducive to master a variety of sales and inventory information, but now most of the system design are not take into account future needs, designing the interface is not flexible enough, so that the current environment after the change are not well adapt to the new environment, resulting in a short lifetime software, in order to achieve the software life extension, you must design software, the whole process of filling into a dynamic anticipatory design, as long as this in the future conditions changed, the software only partially able to make some adjustments to adapt to the new environment.)

定义一个CStudent类，在该类定义中包括：一个数据成员score（分数）及两个静态数据成员total（总分）和学生人数count：成员函数STC(float s)设置分数，求总分，累计学生人数：静态成员函数Sum返回总分；静态成员函数Average求平均值。在main函数中，输入某班同学的成绩，并调用上述函数求全班学生的总分和平均分。(Define a CStudent class in the class definition, including: a data member score (Score) and two static data members total (total score) and the number of students count: the member function STC (float s) set score, find the total score, the cumulative Number of students: the static member function Sum return score static member function Average average. In the main function, enter the results of a class of students seeking the total score and the average score of students in the class and call the above function.)
