long long

Ok thanks I''ll just use that then, but incase I''m require to use a long long as part of the assignment is there anyway I can make it work possiblily typedef or something?

long long isn''t a part of C++, it''s a gcc addin. You can #ifdef for GCC in your code and use long long or __int64 depending on platform. Or since you''re using visual studio just ctrl-h all references before you submit it.

I don''t think there''s an easy way to perform a typedef with a space through any preprocessor.

#if defined(_MSC_VER) || defined(__LCC__) || defined(__INTEL_COMPILER)

#if defined(WIN32)
typedef unsigned long      DWORD;
typedef unsigned char      BYTE;
typedef unsigned short     WORD;
typedef unsigned __int64   QWORD;

#include <basetsd.h>
#else
typedef unsigned __int8    BYTE;
typedef unsigned __int16   WORD;
typedef unsigned __int32   DWORD;
typedef unsigned __int64   QWORD;
typedef signed __int8    INT8;
typedef signed __int16   INT16;
typedef signed __int32	 INT32;
typedef signed __int64	 INT64;
typedef unsigned __int32 UINT32;
#endif

#elif defined(__GNUC__) || defined(__MWERKS__) || defined(__SUNPRO_C) || defined(__DMC__)

typedef unsigned char BYTE;
typedef unsigned short WORD;
typedef unsigned long DWORD;
typedef unsigned long long QWORD;

typedef   signed char		INT8;
typedef   signed short		INT16;
typedef   signed int		INT32;
typedef   signed long long	INT64;
typedef unsigned int		UINT32;

#else
//im just guessing here! - these are not going to be right.

//#error Dont know word sizes for these machines/compilers

typedef unsigned char BYTE;
typedef unsigned short WORD;
typedef unsigned long DWORD;
typedef struct {DWORD a, b;} QWORD;
typedef   signed char		INT8;
typedef   signed short		INT16;
typedef   signed int		INT32;
typedef unsigned int		UINT32;
#endif

there was a template solution on flipcode that ensured you got the correct sized integers iirc. Search for that.

If you need to guess for sizes, "unsigned int" is very likely 32 bits, and "unsigned long" can be 32 or 64, depending on programming model. The 16-bit model is luckily 10 years in the past for all but 0.001% of us :-)

(lp64 == long and pointer are 64 bits == The One True Way)
