Data types

In my program I’m using name as char(60) and country as varchar2(60)
when i trim the values of country varchar2(60) its displaying only one character and when trim the value of name char(60) it prints the whole data.
fro eg: when i trim the values of country detroit it displays only t for name james after timr it displays as james.
can someone explain me why is it so? am’i doing something wrong.
