c-P-P-pointers-and-references-

代码说明：

  C语言的精华和灵魂是“指针”，但运用的时候却比较容易出错。c++又引入了“引用”的概念，好多人不理解它们之间的区别，本人将结合自己的使用经验，给出一些编程的实例，简单阐述它们之间的区别。(C language, the essence and the soul is "pointer", but the use of it has been more prone to error. c++ and the introduction of the "reference" concept, a lot of people do not understand the difference between them, I will combine their experience, give some programming examples, briefly discusses the differences between them.)
