You need to learn to solve these problems yourself, or you're not
learning anything.

The compiler tells you the type "time_put" is not defined, so you
probably haven't included the header that defines it.
Look at any reference (e.g.
http://dinkumware.com/manuals/default.aspx?manual=compleat&page=locale2.html#time_put
or http://cplusplus.com/reference/std/locale/time_put/) and you'll
find you need to #include <locale>
