Windows Data Type exploration (4)

This table is the data type supported by the visual C ++ 7.1 compiler, that is, the "root" of various data types in windows.

Data Type name	Bytes	Alias	Value Range
Int	*	Signed, signed int	Determined by the operating system, that is, it depends on the operating system's "font"
Unsigned int	*	Unsigned	Determined by the operating system, that is, it depends on the operating system's "font"
_ 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
Bool	1	None	False or true
