However, in theory, you can also use the size of an int as a reference,
The judge is 32-bit or 64-bit.
sizeof (int) = = 4//32-bit system.
sizeof (int) = = 8//64-bit system.

You can also use the following functions:

BOOL IsWow64 () {     *lpfn_iswow64process) (HANDLE, pbool);     Lpfn_iswow64process fniswow64process;      = FALSE;      = (lpfn_iswow64process) GetProcAddress (GetModuleHandle ("kernel32"),"  Iswow64process");      if (NULL! = fniswow64process)     {         fniswow64process (getcurrentprocess (),&bIsWow64);    }      return
