string::operator<< (STL Sample)

The sample code below illustrates how to use the string::operator<< STL function in Visual C++.

Required Header:
<string>

   template<class _E, class _TYPE, class _A> inline
   basic_ostream<_E, _TYPE>&
   operator<<( basic_ostream<_E, _TYPE>& OStream,
               const basic_string<_E, _TYPE, _A>& XString);

Note: The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.

Description:
The operator<< is used to insert a string into an output stream.
