100 个 4 位任意的十六进制数,设计程序将这些数由小到大进行排序。本程序采用的方法是冒泡排序法。-100 four arbitrary hexadecimal number, the number of small to large design process to sort these. This program uses a method of bubble sort, that way from start to finish using a loop repeatedly make adjacent pairwise comparison of two numbers, so large numbers moved to the back, and with a flag CHANGE, if it appears two the number of exchange, the flag will CHANGE 1, the cycle will continue. When CHANGE = 0 时 means there is no exchange, sorting has been completed, the cycle ends.
