编程实习作业

某一应用管理一批数据，数据可按其输入顺序号提取（例：取第二个输入数据），同时要求可按其大小顺序提取（例：取数据中第二大的数据）。有另一应用需要在原基础上为每个数据附加一个参数，此参数给出该数据与全体数据的均差（该数据与全体数据的算术平均值之差的绝对值），并且数据和均差均可按顺序号或大小顺序提取（均差顺序号与数据顺序号相同，均差大小与数据大小分别排序）。试用面向对象方法对如上应用程序设计一个类结构，给出每个类应包含的属性和方法。要求先实现第一部分功能，再实现第二部分功能，使用类的继承和重用技术，用C++实现。-Programming Internship jobs

An application management number of data, data extraction according to their input sequence number (example: take the second input data), also asked the size of the order can be extracted (for example: take the data the second-largest data). Another application requires data on the original basis for each additional parameter, this parameter is given the data and all the data are poor (the data and all the data, the arithmetic mean of the absolute value of difference), and data and have poor may order number or size of the sequential extraction (mean difference, the data sequence number and the same sequence number, size and data size are poor sorting, respectively). Try object-oriented method to design a class above the application structure, gives each class should contain the properties and methods. The first part of the functionality required to first achieve and then achieve the second part of the function, use class inheritance and reuse of technology
