输入N个点的坐标，判断这N个点能否构成一个凸多边形。(Enter the coordinates of N points, to determine whether the N points form a convex polygon.)

说明：  一个实现外部排序的程序，其中gnerate.cpp为产生一个随机的文件，用于被排序。而caculate.cpp为外部排序程序。(A realization of the external sort program, which gnerate.cpp to generate a random file for be sorted. The caculate.cpp external sort program.)

该代码实现了深拷贝的问题，对于深拷贝进行了一系列的介绍，并且显示其与浅拷贝的区别。(A deep copy of the code issues a series of deep copy for presentation, and shows the difference between a shallow copy.)

2008软件公司面试题:排序大全：简单选择排序、冒泡排序、选择排序、shell排序、快速排序、插入排序、堆排序(从小到大)、归并排序（利用递归）(2008 software companies face questions: Sort Guinness: simple choice to sort, bubble sort, select sort, shell sort, quick sort, insert sort HEAPSORT (from small to large), Merging Sort (recursive))

冒泡优化： 如果一个序列是int n[]={1,2,3,4,5,6,7,8,9} , 用正常的冒泡排序需要排8次才行，优化之后1次就好，也就是说序列越接近于正常序列，改进之后的冒泡排序的次数就越少，这样会给一个冒泡排序算法带了很大的效率。 思想：添加一个boolean变量用来判断冒泡是否是已经排好了顺序，如果boolean的值为false，说明是已经排好了，如果boolean的值true，说明没有排好，继续排。(If a sequence is int n [] = {, 1,2,3,4,5,6,7,8,9} need to row 8 times the job after optimization times like normal bubble sort, but alsomeans that the sequence is more close to the normal sequence, improved bubble sort, the less the number, which would give a bubble sort algorithm with a great deal of efficiency. Idea: add a boolean variable used to determine the bubble whether it is already lined up the order, if the boolean is false, indicating already lined up, if the boolean value of true, did not line up, continue to row.)
