Doing so makes it clear that what is being operated on is a pointer to an array element, not the array itself.
这样就明确地表示，函数操纵的是指向数组元素的指针，而不是数组本身。
An array variable holds a pointer to an array object, which holds the array elements and the rank and length information.
数组变量保存指向数组对象的指针，而数组对象保存的是数组元素、秩和长度信息。
