Re: [Dev-C++] Differences in compilers

[Jason H. <jas...@bt...>]

Try writing NULL in all caps. AFAIK most definitions of NULL are done =
all in upper case letters. If I remember correctly NULL is normally =
defined thus:

#define NULL (void*) 0;

Although that could be wrong. In the end all NULL are effectivly zero in =
one form or another.

  Hey guys this is probably a really stupid question but I got a problem =
I feel is totally compiler related.  I'm still using a book called "C++ =
PROGRAMMING for the Absolute Beginner," and its compatible with a =
compiler called "CODE WARRIOR". I have typed out a very simple code for =
Windows 32 apps and I have an error "NULL not declared," and  below is =
the code.  I was just wondering what I might have to adjust or keep in =
mind when dealing with different compilers because the author figures =
this will run no problem.=20

  #include <windows.h>
  //win32 entry-point routine
  int WINAPI WinMain(HINSTANCE hInst,
                     HINSTANCE hPreInst,=20
                     LPSTR lpszCmdLine,=20
                     int nCmdShow)
  {
      MessageBox(Null, "Windows Programming is Easy!!",
                       "My First Message Box",
                       MB_OKCANCEL | MB_ICONINFORMATION);
  }
