<DIV></DIV>1)After checking the assert.h header file included in cygwin, I saw this
<DIV></DIV>
<P>/*<BR> assert.h<BR>*/</P>
<DIV></DIV>
<P>#ifdef __cplusplus<BR>extern "C" {<BR>#endif</P>
<DIV></DIV>
<P>#include "_ansi.h"</P>
<DIV></DIV>
<P>#undef assert</P>
<DIV></DIV>
<P>#ifdef NDEBUG /* required by ANSI standard */<BR>#define assert(p) ((void)0)<BR>#else</P>
<DIV></DIV>
<P>So you see why it still compiled even without being in debug mode. You are required to define NDEBUG.</P>
<DIV></DIV>
<DIV></DIV>
<DIV></DIV>
<DIV></DIV>2) Different compilers handle assert differently, but in this case, the message is sent to the console window, so I suggest running the program from the console and see the result. If you have VC++6, try this program.
<DIV></DIV>
<P>#define WIN32_LEAN_AND_MEAN<BR>#include <windows.h><BR>#include <stdlib.h><BR>#include <cassert><BR>int __stdcall WinMain(HINSTANCE,HINSTANCE,LPSTR,int)<BR>{<BR> int a=5;<BR> int b=1;<BR> assert(a<b);<BR> system ("PAUSE");<BR> return 0;<BR>}</P>

<P>It'll give you the message box you so desire :)</P>
