Simple maybe, but confusing at first.

With NOTHING in the function main() or WinMain(), make your program display a window, or, just message box. :D

Make an empty program and then hex edit it randomly so you get some kind of error :p

#define something silly.

#define main(){ main(){display a window, or, just message box.

int main(){}

Heh, don't even have to hexedit it. Just open it with notepad or something, and write your name somewhere :p

:p

Actually, I meant by your program, not by the OS's confusion.
And not with a #define either.

Code:

---

class foo {
  int *p;
  public:
    foo() {
      p = 0; *p = 0;
    }
};
foo bar;
int main ( ) { return 0; }

I get a nice "would you like to tell Microsoft about this problem" message popup :)
Do whatever you like in the constructor for your globals to avoid writing any code in main

Code:

---

#include <windows.h>

class MsgBox
{
public:
  MsgBox() { MessageBox(NULL,TEXT("Hello!"),TEXT("Rock!"),MB_OK); }
};

MsgBox mb;

int main()
{
}

Yes, that's exactly what I was thinking of.

I always found this one interesting

Code:

---

class parent
{
private:

public:
        parent()
        {
                cout<< "CONSTRUCTOR!";
        }
};

parent dsfdf;
int main( void )
{
    return 0;
}
