这个小程序是在C语言编程里一个非常重要的算法。虽然，它的代码量很少，但是它能在最短的时间内，花费系统最少的资源完成从小到大（或者从大到小的排序），在学习C语言的初期，这是一个非常好的程序。-This small program in C language programming in a very important algorithm. Although it is small amount of code, but it can in the shortest possible time, to spend a minimum of system resources to complete small to large (or descending sort), in the early stages of learning the C language, this is a very good program.
