How to assign pointer address manually in C programming language?

Question

How do you assign a pointer address manually (e.g. to memory address 0x28ff44) in the C programming language?

Answer 1

Like this:

void * p = (void *)0x28ff44; 

Or if you want it as a char *:

char * p = (char *)0x28ff44; 

...etc.

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; 

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