1、　　演示程序对6种内部排序算法（堆排序、直接插入排序、简单选择排序、快速排序、希尔排序、归并排序）作输入实测比较。

2、　　待排序表的元素的关键字为整数。用户可输入不同数据作测试比较。比较的指标为关键字参加的比较次数（用compCount计量）和关键字的移动次数（用shiftCount计量，关键字交换计为3次移动）。

3、　　演示程序以用户和计算机的对话方式执行，即在计算机终端上显示“提示信息”下，用户可由键盘输入待排序表的表长（不大于20）和数据。

4、　　每次测试完毕，显示各种排序比较指标值和排好序的数据。

-1, the demonstration program on six internal sorting algorithm (Heap Sort direct insertion sequence and simple choice ranking Quick Sort, Hill sorting, merging ranking) for the importation of experimental comparison. 2, the ranking table to be elements of the keyword as an integer. Users can input data for testing different comparison. Comparable indicators to compare the keyword in the number of (using compCount measurement) and the mobile number keyword ( shiftCount use metering, the keyword exchange dollars for the 3rd Mobile). 3, the demo program to computer users and implementation of the dialogue, that is displayed on the computer terminal, "a message", Users can sort the keyboard input to be in table (not more than 20) and data. 4, each test completed, showing the sort ind
