指針運算符

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.

指針是初學者學習C中更複雜的主題之一，可以寫絕大多數的Arduino草圖，而不會遇到指針。然而，為了操縱某些數據結構，使用指針可以簡化代碼，並且操作指針的知識在工具包中是可行的。
