You are trying to use the GNU String class (note the capital S). This is 
included in libgpp, which is deprecated. This class is not defined in the 
standard and it is not portable.
Better use the standard string class (note the lowercase s) by including 
<string> (note the missing ".h").

You can find documentation for this class in any book on standard C++ (e.g. 
Stroustrup's "The C++ Programming language", 3rd ed.). 
Or on the web (e.g. http://www.dinkumware.com/refcpp.html).
