From the minimum and maximum values, you can deduce that
`short int' is *at least* sixteen bits wide. But it might be
eighteen bits wide, or twenty-eight, or thirty-two, or ...

Not at all. Something that is "implementation-defined" means

SHRT_MIN and UINT_MAX are documentation of the implementation's

If I may rephrase your question slightly, you have asked
"لما क्यों किसी को *ी चार अन्य 8 बिट होना चाहेगा". In this form, the
question may well answer itself.
