Thread: Virtual Functions

IM getting an error, and have no idea what the cause is.. Im creating a virtual class function and its driving me nuts..

I get the following:

Code:

square.cxx:6: error: virtual outside class declaration
square.cxx:8: error: virtual outside class declaration
square.cxx:10: error: virtual outside class declaration
square.cxx:13: error: virtual outside class declaration

Here is my square class:

Code:

class square {
   public:
      square();
      virtual ~square();
      virtual void read(istream &in);
      virtual void display() const;

   protected:
      string name[30];

};

and here is code.cxx

Code:

square::square(){};

virtual square::~square(){};

virtual void square::read(istream &in) {
   cout << "test\n";
}
virtual void square::display() const {}

I just dont understand how I am using "virtual" outside of the class????

or what the compiler is complaining about....

thanks for any assistance/explanation...

haha... your a lifesaver... or in my case I should say you just saved me from becoming bald 10 yrs early :-).

the same applies for the static (vars and functions), and friend keywords, as far as can recall now.
