Nettet4. aug. 2024 · A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.

http://projectpython.net/chapter02/ Nettet2. aug. 2024 · The int and unsigned int types have a size of four bytes. However, portable code should not depend on the size of int because the language standard allows this to be implementation-specific. C/C++ in Visual Studio also supports sized integer types.
