Size of int in 64 bit machine
Webb[1] : 7–10 Subsets support small embedded systems, personal computers, supercomputers with vector processors, and warehouse-scale 19 inch rack -mounted parallel computers . The instruction set specification defines 32-bit and 64-bit address space variants. WebbIf int was 64 bits, then you couldn't have all three of the sizes 8, 16 and 32 bits. That's why compilers tend to make int = 32 bits, so you can have char = 8 bit, short = 16 bit, int = 32 …
