24.7 STRINGS

class String

    { private:      int len;      string80 a ;    public:      String( string80 p);      String();      void show();      friend ostream& operator<<(ostream & , String st) ;      String operator + (String st2);  };

String is an inseparable part of modern day programming. Newer compilers will have this as inbuilt class. Otherwise, the above definition is good enough.
