Hands-On System Programming with Go

Integers

In C, the types of integers available have a number of similarities with Go, since there are signed and unsigned versions of each integer type in both languages, but they differ in terms of name and byte size. The C sizeof function makes it possible to check the size for each of these types.

Here is a list of integer types that are available in C:

Signed types

Type	Size	Range
char	1 byte	[-128, +127]
int	2 or 4 bytes	see short and long
short	2 bytes	[-32 768, +32 767]
long	4 bytes	[-2 147 483 648, [phone]]
long long	8 bytes	[-9 223 372 036 854 775 808, [phone] 775 807]

 

Unsigned types

Type	Size	Range
unsigned char	1 byte	[0, +255]
unsigned int	2 or 4 bytes	see unsigned short or unsigned ...
