Re: parameters and return value of main() in C?

Now that I look at your code again, the problem is obvious. (Or one problem is obvious anyway. :-)) Finally, you know that compilers let you embed asm in C source, right? If you're just playing around that's totally cool, but I figured I'd ask. You're right (and I'm ashamed not to have noticed by m...

I don't know a lot of C, I definetely know much more assembly, but I'm messing around with executable arrays (just out of curiosity), such as this: #include <stdlib.h> #include <stdio.h> int main() { char a[] = { 0x8b, 0xc1, //mov eax,ecx (with the fastcall convention the first parameter is in ecx) ...

I'm nitpicking here, but that is not necessarily true, it is consistent with ZF that ℝ is a countable union of countable sets, you need (at least) ACω to prove that the countable union of countable sets is countable.
