2You need to deal with `unsigned` here. This is _not_ an advanced question, sorry. – ForceBru Mar 05 '15 at 14:58

When a signed int is operated with unsigned int then it is converted to unsigned int. Since -16 can't be represented as unsigned int, maximum value that can be represented ny unsigned int (UINT_MAX) is added to -16.

2*"Since -16 can't fit into unsigned int"* It's not a matter of not *fitting*. – T.J. Crowder Mar 05 '15 at 15:00
