string::operator<< 

Illustrates how to use the string::operator<< Standard Template Library (STL) function in Visual C++.


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);

NoteNote

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

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