Data type Range

Data type range.

Below find out the list of data type range for C++. I got the list from MSDN: ttp://msdn.microsoft.com/en-us/library/s3f49ktz(VS.71).aspx

Type Name	Bytes	Other Names	Range of Values
int	*	signed, signed int	System dependent
unsigned int	*	unsigned	System dependent
__int8	1	char, signed char	–128 to 127
__int16	2	short, short int, signed short int	–32,768 to 32,767
__int32	4	signed, signed int	–2,147,483,648 to 2,147,483,647
__int64	8	none	–9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
char	1	signed char	–128 to 127
unsigned char	1	none	0 to 255
short	2	short int, signed short int	–32,768 to 32,767
unsigned short	2	unsigned short int	0 to 65,535
long	4	long int, signed long int	–2,147,483,648 to 2,147,483,647
unsigned long	4	unsigned long int	0 to 4,294,967,295
enum	*	none	Same as int
float	4	none	3.4E +/- 38 (7 digits)
double	8	none	1.7E +/- 308 (15 digits)
long double	10	none	1.2E +/- 4932 (19 digits)
