为什么我们有除void以外的指针 [英] Why do we have pointers other than void

问题描述

我知道我们有不同的指针，例如int，float和char. void指针是唯一可以容纳所有其他指针的指针.

I know that we have different pointers like int, float, and char. A void pointer is the only pointer which can hold all others.

是否存在其他指针仅仅是为了灵活地执行指针算术?

Do the other pointers exist only for the flexibility to do pointer arithmetic?

还有其他原因导致C语言中存在除void之外的其他指针吗?

Is there any other reason that pointers other than void are present in C language?

推荐答案

类型安全.定义指针的类型有助于编译器在尝试通过指针使用错误类型的数据时发现错误.这就是C首先具有类型的原因.

Type safety. Defining the type of pointers helps the compiler find errors where you are trying to use data of the wrong type through a pointer. That's the reason C has types in the first place.
