如何比较指针？ [英] How to compare pointers?

问题描述

假设我有两个指针：

int *a = something;
int *b = something;

如果我想比较他们，看看他们是否指向同一个地方）work？

If I want to compare them and see if they point at the same place does (a == b) work?

推荐答案

是的，这是指针相等的定义：它们都指向同一位置href =http://en.wikipedia.org/wiki/Pointer_aliasing>指针别名）

Yes, that is the definition of pointer equality: they both point to the same location (or are pointer aliases)
