The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible traits class.

Since string is used extensively, C++ provides a built-in string data type. Just like int, float or other data types, we can use string data type also. It simply makes using strings easier. Same as cin and cout, string is also defined in the std namespace. To use strings in this way, we need to include the header since it is declared in the header.
