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.

If not, you actually create less than 16-bit number. For example your new number can be so small that it can be fit in 8-bit. For your example, 0x68 is not a 16-bit number. it is 8-bit number. – Ahmet Dundar Sep 28, 2024 at 16:50 orange cat cartoon head

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. On 32-bit systems, like the ARM based Due, it's 32 bits, so 4 bytes. WebThere are 5 basic numerical types representing booleans (bool), integers (int), unsigned integers (uint) floating point (float) and complex. Those with numbers in their name indicate the bitsize of the type (i.e. how many bits are needed to represent a single value in memory).
