箭头操作符（ - ＆GT;）用法在C [英] Arrow operator (->) usage in C

问题描述

我目前正在读称为一个良好的入门书学习C自学℃的21天（我已经学会了Java和C＃，所以我以更快的速度移动）。我正在读的指针章和 - >（箭头）运算符上来没有任何解释。我认为这是用于调用部件和功能（像。（点）运算的等效的，但对于指针而不是成员）。但我不能完全肯定。我能请得到一个解释和code样？

I am currently learning C by reading a good beginner's book called "Teach Yourself C in 21 Days" (I have already learned Java and C# so I am moving at a much faster pace). I was reading the chapter on pointers and the -> (arrow) operator came up without explanation. I think that it is used to call members and functions (like the equivalent of the . (dot) operator, but for pointers instead of members). But I am not entirely sure. Could I please get an explanation and a code sample?

推荐答案

foo-＆GT;酒吧等同于（*富）的.bar ，也就是说，它被调用成员栏从结构的富点。

foo->bar is equivalent to (*foo).bar, i.e. it gets the member called bar from the struct that foo points to.
