The template class describes the storage and member functions common to both input streams (of
template class basic_istream) and output streams (of template class basic_ostream) that
depend on the template parameters. (The class ios_base describes what is common and not
dependent on template parameters. An object of class basic_ios<Elem, Tr> helps control a
stream with elements of type Elem, whose character traits are determined by the class Tr.
An object of class basic_ios<Elem, Tr> stores:
a tie pointer to an object of type basic_ostream<Elem, Tr>●
a stream buffer pointer to an object of type basic_streambuf<Elem, Tr>●
