Description: 从数据文件records.txt中读取学生信息，建立与源数据同序的学生链表并打印在屏幕上；
统计学生链表中身高达标人数（男女生的身高达标值由键盘输入），并打印结果；
对上述学生链表按学号进行排序，然后将一位学生的相关信息插入到已按学号排序的学生链表中后仍然保持学号的有序性，将结果链表打印在屏幕上；
对上述操作后的学生链表进行倒置，结果输出到数据文件result.txt中；
删除链表中身高为指定值的所有学生结点并打印；
将当前的学生链表拆分为男生链表和女生链表（没有新结点生成），分别打印到屏幕上。-Read from the data file records.txt student information, the establishment of the same order with the source data and print the list of students on the screen

Description: 本示例主要的功能是通过给定的一组成绩数据绘制出成绩的分布图（包括直方图和圆饼图）。这里没有用到数据库，因为是一个简单的成绩分布图，而用数据库的话在转到另一台机子上还要重新建表，对于学生信息也要涉及到录入问题，不容易实际操作，所以本示例采用了更为方便的通过手动录入数据或者是从文件（txt格式文本文档，第一个数为总人数，其余为分数，分数之间用逗号隔开）导入数据两种方式绘制出其统计图。录入的成绩可查看可修改，直方图采用了立体图模式，看起来更直观，各个分数段都有明显的分数人数标注，看起来直观形象。饼形图也同样标注了各颜色对应的分数段及人数，看起来很直观。数据录入部分与绘图部分集成在一个对话框上面，没有在单个文档中调用，减少了不必要的繁琐过程-The main feature of this example is given a set of performance data to map out the distribution of results (including histograms and pie charts). Database is not used here because the result is a simple map, but with the words in the database to another machine on the table but also to re-build, but also for the student information related to the input problem, is not easy to practice, so this example by using a more convenient data entry or manual from file (txt format text documents, the first number is the total number of rest points, scores, separated by commas) two ways to import data to map out their charts . Entry can be modified to view the results, using a three-dimensional histogram graph model, it seems more intuitive, each segment has a significant fraction of the number of marked points, it seems intuitive image. Pie charts are also marked with the color and number of segments corresponding to the score, it seems very intuitive. Data entry and some portion of the drawing i
