WebC99 has defined a set of fixed-width integers that are guaranteed to have the same size on any architecture. These can be found in stdint.h header. C++ officially adopted these fixed-width integers as part of C++11. They can be accessed by including the cstdint header, where they are defined inside the std namespace.

WebA uint16_t is an unsigned 16 bit value, so it takes 2 bytes (16/8 = 2) The only fuzzy one is int. That is "a signed integer value at the native size for the compiler". On an 8-bit system like the ATMega chips that is 16 bits, so 2 bytes.
