(1)设计一个人事管理的People(人员)类.考虑到通用性,这里只抽象出所有类型人员都具有的属性:name(姓名),number(编号), sex(性别),birthday(出生日期),id(身份证号)等等.其中"出生日期"定义为一个"日期"类(具有属性:year(年),month (月),date(日)内嵌子对象.用成员函数实现对人员信息的录入和显示等必要功能操作(自己独立思考设计).要求包括:构造函数和析构函数,拷贝构造 函数,内联成员函数. (2)从People(人员)类派生出student(学生）类，添加属性：班号char chassNO［７］；从People类派生出teacher（教师）类，添加属性：职务char principalship［１１］，部门char department［２１］．从student类中派生出graduate（研究生）类，添加属性：专业char subject［２１］，导师teacher adviser（为（教师类内嵌子对象）；从graduate类和teacher类派生出ＴＡ（助教生）类，注意虚基类的使用，重载相应的成员函数． （３）对People类重载＂＝＝＂运算符和＂＝＂运算符，＂＝＝＂运算符判断两个People类对象的id属性是否相等；＂＝＂运算符实现People类对象的赋值操作． （４）定义一个对People类对象数组按编号排序的函数，一个按编号查找people对象的函数．

用pascal编一个年历具体要求是：设计电子月历的程序 一、任务内容（task） 1．设计的程序应具有以下功能： （1）任意输入某年的某一月份，屏幕应能显示该月的月历； （2）应允许多次从键盘输入某月份,并自行设置结束标志。 （3）如在屏幕上输入2007年12月份的信息,屏幕的显示形式如下： month Sun. Mon. Tue. Wed. Thu. Fri. Sat. 12 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 （4）备注：输出界面也可以是其它形式，另外还可对输出界面进行必要的修饰（如：加入表格线）。 2．程序设计要求： 1）采用结构化的程序设计方法进行编程； 2）用case控制语句实现选择分支结构； 3）用while \repeat…until\for语句实现循环结构； 4）利用标准过程readkey实现程序执行暂停； 5）利用标准过程 clrscr实现清屏操作。

udp-cast!可以用multicasting的方式把檔案傳送到一個群組，很好用~~~~!有興趣的人式式吧。 1.先make 2.會產生兩個兩進位檔，sender用來擴播檔案 詳細就man udp-cast吧

OTSU Gray-level image segmentation using Otsu s method. Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern. 9:62-66 1979). Thresholds are computed to maximize a separability criterion of the resultant classes in gray levels. OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the corresponding Iseg is therefore a binary image. The pixel values for Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ... [Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability criterion within the range [0 1]. Zero is obtained only with images having less than n gray level, whereas one (optimal value) is obtained only with n-valued images.

WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization. The problem addressed has been tackled for 1-D linear array and further extended to 2-Dimensions as stated in the next slides.

Maya Calendar During his last sabbatical, professor M. A. Ya made a surprising discovery about the old Maya calendar. From an old knotted message, professor discovered that the Maya civilization used a 365 day long year, called Haab, which had 19 months. Each of the first 18 months was 20 days long, and the names of the months were pop, no, zip, zotz, tzec, xul, yoxkin, mol, chen, yax, zac, ceh, mac, kankin, muan, pax, koyab, cumhu. Instead of having names, the days of the months were denoted by numbers starting from 0 to 19. The last month of Haab was called uayet and had 5 days denoted by numbers 0, 1, 2, 3, 4. The Maya believed that this month was unlucky, the court of justice was not in session, the trade stopped, people did not even sweep the floor.
