Number one, the basic structure is that you have a pointer and it points over to a pointee, but the pointer and pointee are separate and the common error is to set up a pointer but to forget to give it a pointee.
第一，基本结构是，你有一个,指向数据的指针，但是那个指针和数据,是分开的，通常错误是声明了一个指针,但是没有指向一个数据。
-
Or another way of thinking about it, is remember I said when I call that class definition it creates an instance, that's a pointer to some spot in memory that's got some local information around it.

Number three, pointer assignment, takes one pointer and changes it to point to the same pointee as another pointer so after the assignment the two pointers will point to the same pointee.
第三条，指针赋值，使一个指针,指向另外一个指针所指向的数据,赋值过后，两个指针会指向,同样的数据。

Scratch This Boolean expression allows you to say to scratch if you are touching the mouse pointer, the little arrow, do something. How do we do something?

So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.
所以我们看到我们用激光笔,还是没有逐出电子，即使我们有这样的强度，它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。
