说明：  指针为C语言编程提供了强大的支持——如果你能正确而灵活地利用指针，你就可以直接切入问题 的核心，或者将程序分割成一个个片断。一个很好地利用了指针的程序会非常高效、简洁和精致。
(Pointer for the C programming language provides a powerful support- If you can correct and flexible use of indicators, you can directly into the core of the problem, or a program is separated into fragments. A very good use of pointer procedures would be very efficient, simple and refined.)
