	자료형	크기	범위
논리형	bool	1 byte (8 bit)	0 ~ 1
문자형	(signed) char	1 byte (8 bit)	-128 ~ 127
	unsigned char		0 ~ 255
정수형	(signed) short (int)	2 byte (16 bit)	-32,768 ~ 32,767
	unsigned short (int)		0 ~ 65,535
	(signed) int	4 byte (32 bit)	-2,147,483,648 ~ 2,147,483,647
	unsigned int		0 ~ 4,294,967,295
	(signed) long (int)	4 byte (32 bit)	-2,147,483,648 ~ 2,147,483,647
	unsigned long (int)		0 ~ 4,294,967,295
	(signed) long long (int)	8 byte (64 bit)	-9,223,372,036,854,775,808 ~ 9,223,372,036,854,775,807
	unsigned long long (int)		0 ~ 18,446,744,073,709,551,615
실수형	float	4 byte (32 bit)	3.4E+/-38(7개의 자릿수)
	double	8 byte (64 bit)	1.7E+/-308(15개의 자릿수)
	long double	8 byte (64 bit)	double과 동일
