It's supposed to change the value at 0x100579C. I don't see anything wrong with it. But when I run the code, the compiler produces an error.Code:#include <iostream>
using namespace std;
int main()
{
int * pointer = 0x100579C; //ERROR ZONE
*pointer = 1;
delete pointer;
system("PAUSE");
return 0;
}
How would you fix this? Thanks!Quote:

I think the compiler is just trying to tell you that you're about to do something bad (i.e. assigning a number to a pointer). You can easily cast away this error, but you'd crash very soon after running the program, since you have no idea who owns the memory at address 0x100579C.
Then you try to delete a pointer which you didn't new. If the *pointer = 1; didn't kill you, the delete surely would.
"0x100579C" is an integer. You need to cast it as a pointer to an integer. e.g, (int*)
I took away the delete. How do I cast it as a pointer to an integer? The example was hard to follow. Like, a longer example. Thanks!!
int * pointer = (int*)0x100579C; //ERROR ZONE
Thank you! Yeah, the program didn't work but atleast I learned something. It didn't exactly crash, I got a error message and it exited. Anyway, thanks!
this is c-style cast - that should be probably left to C...

What makes you think that's not crashing?Quote:

It is because his harddisk was still working, and no other hardware was springing out of the desktop to splash into 1000 little pieces arond his room... ;)Quote:
