一个好的DataGrid，实现自动排序，百万数据集处理

2D图像渲染，比如反走样，mark等效果，编码风格很好，模版用的淋漓尽致(2D image rendering, such as anti-aliasing, mark, such as the effect of good coding style, the template used by most)

链表，递归结构，结构指针变量，将链表数据从尾到头打印出来(List, recursive structure, the structure pointer variable, data from the end of the list printed Daotou)

求用户从键盘输入的一个日期对应的是星期几(Seeking user input a date from the keyboard corresponding to the week)

说明：  another incremental change is made to the new solution, and so on until no further improvements can be found.

说明：  AR程序设计4，扫描图片可以出现三维模型，并操作(AR programming 4, scanning pictures can appear three-dimensional model, and operation)

这个图纸是很多人需求的,下载后不会后悔.(The drawing is a lot of people demand, download, will not regret it.)

　　编写一通用的预测法分析程序，要求有一定的错误处理能力，出错后能够使程序继续运行下去，直到分析过程结束。可通过不同的文法（通过数据表现）进行测试。(Write a generic prediction analysis procedure that requires a certain degree of error-handling capabilities, enabling the program to continue after an error to run it until the end of the analysis process. Can be tested by different grammar (by performance data).)
