Right? I've allocated a variable, it happens to be a pointer; it's still a variable, who know what's in it, right?
对不?我分配了一个变量,它碰巧是一个指针,它还是一个变量,谁知道它里面是什么?
It actually lets you see how to get access to that pointer so you know what you're referring to.
怎么来取得指针,以得知在对什么进行操作,但是这是个简单的设计决定。
Instead if we want this pointer to represent the address of something in as much as it points at that address let's just draw an arrow.
如果我们想要让这个指针表示,数据的地址,它指向的地址,我用一个箭头表示。
