In C on a 32-bit system, which data type will store (and can therefore print) the largest integer? Is it long long or unsigned long? Is there an unsigned long long? And which is the most precise and politically correct?
Your question is a bit unclear, but
intmax_tis the largest signed integer-valued type (anduintmax_tis the largest unsigned integer type). These are typedefs defined in<stdint.h>, but if you are printing them, you need<inttypes.h>instead, and the PRInMAX macros for various values of n.
