如何用C编程语言手动分配指针地址？
例如内存地址是0x28ff44

How to assign pointer address manually in C programming language? for example memory address is 0x28ff44

推荐答案

这样的：

void * p = (void *)0x28ff44;

或者，如果你想把它当作一个的char * ：

char * p = (char *)0x28ff44;

...等。

如果你指着东西，你真的，真的不是为了改变，添加一个常量：

If you're pointing to something you really, really aren't meant to change, add a const:

const void * p = (const void *)0x28ff44;
const char * p = (const char *)0x28ff44;

...因为我想这一定是某种著名地址和那些通常（尽管总是没有办法）只读的。

...since I figure this must be some kind of "well-known address" and those are typically (though by no means always) read-only.
