指针运算符

Pointers are one of the more complicated subjects for beginners in learning C, and it is possible to write the vast majority of Arduino sketches without ever encountering pointers. However for manipulating certain data structures, the use of pointers can simplify the code, and and knowledge of manipulating pointers is handy to have in one's toolkit.

指针是初学者学习C中更复杂的主题之一，可以写绝大多数的Arduino草图，而不会遇到指针。然而，为了操纵某些数据结构，使用指针可以简化代码，并且操作指针的知识在工具包中是可行的。
