Integer Types

Integer data type lists the name, size, and range of the integer data types.

Table 1. Integer data type
This type	has this size	and holds this range of values
`short`	16 bits	-32,768 to 32,767
`unsigned short`	16 bits	0 to 65,535
`int`	32 bits	-2,147,483,648 to 2,147,483,647
`unsigned int`	32 bits	0 to 4,294,967,295
`long`	32 bits	-2,147,483,648 to 2,147,483,647
`unsigned long`	32 bits	0 to 4,294,967,295
`long long`	64 bits	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
`unsigned long long`	64 bits	0 to 18,446,744,073,709,551,615

The compiler recognizes the long long data type when pragma longlong is on or when compiling C99 source code (ISO/IEC 9899-1999 standard).
