The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.

For a 16-bit integer, use uint16_t. These are defined in stdint.h . These are traditionally called "short integers" or "half integers" and require the %hu qualifier in printf or similar functions, rather than just %u (which stands for unsigned int , whose size depends on the target machine.)

20.1 Integers. The C language defines several integer data types: integer, short integer, long integer, and character, all in both signed and unsigned varieties. The GNU C compiler extends the language to contain long long integers as well.

The implementation may define typedef names intN_t, int_fastN_t, int_leastN_t, uintN_t, uint_fastN_t, and uint_leastN_t when N is not 8, 16, 32 or 64. Typedef names of the form intN_t may only be defined if the implementation supports an integer type of that width with no padding.

Represents an unsigned integer number stored with 8, 16 or 32 bit. Type syntax. uint8. uint16. uint32. Literal syntax. decimal‑literal. 0x hex‑decimal‑literal. Discussion. The number of bits determines directly the range for the respective values: The unsigned integer numbers may be expressed in either decimal or hexadecimal notation.

uint16_t is unsigned 16-bit integer. unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX is 65535 ).

You are likely wondering what are uint8_t, uint16_t, uint32_t and uint64_t. That's a good question. Because it could be really helpul! It turns out that they are equal respectively to: unsigned char, unsigned short, unsigned int and unsigned long long. But what are ranges of all these types? Let's test it in this C type tutorial ...

On one machine, it might be 32 bits (the minimum required by C). On another, it’s 64 bits. What do you do if you want an integer type that’s precisely 32 bits long? That’s where int32_t comes in: it’s an alias for whatever integer type your particular system has that is exactly 32 bits.

This header was originally in the C standard library as <stdint.h>. This header is part of the type support library, providing fixed width integer types and part of C numeric limits interface.
