WebAug 10, 2016 · Use the predefined types short, int, long, et al when they're good enough for your purposes and you don't want to use the longer names. short and int are both guaranteed to be at least 16 bits, long at least 32 bits, and long long at least 64 bits. int is normally the "natural" integer type suggested by the system's architecture; you can think … WebSmaller programs execute faster then larger ones because the CPU can fit more of the program in the faster L1/L2/L3 caches. Using the int type can result in fewer CPU instructions however it will also force a higher percentage of the data memory to not fit in the CPU cache.
