size of int* ??

I got bored so i made this program that clears up system memmory, it works realy well and clers 224MB out of my 256. It creates a lot of int* on the heap/free store. The only problem is that an int* should be 4 bytes but the program seems to be eating up memmory a lot faster, about 8 times faster, weird, heres the code: #include <iostream.h> int main() { int* stand = 0; int i = 0; int megcount = 0; while(1) { stand = new int; i++; if(i==(256*1024) { i=0; megcount++; cout << megcount << "\n"; cout << flush; } if(stand==0) { cout << "cleared " << megcount << " MB of memmory ;)\n"; return 0; } } return 0; } anybody know why/what did i do wrong?

Knowing the limits of your system can be quite constructive. That's why you're allowed to sell books on hacking, because they're there so you know how the hackers do it and you can design your systems to prevent it.

I've done tests to see what can and can't be done. It's quite useful. In the case of what Psyco did, it's useful for finding out if your compiler or OS is managed, etc. Hopefully I never find a command by the name of CreateMagicProcessorSmoke(); when I'm testing...
