Virtual methods

[JRevor]

I have a class called Celula, which has a virtual method called simbolo

      virtual char simbolo(void) const; 

I want to declare the body of the method , outside the class. What is the syntax?
(here's an example of what i wanted to do)

//This header is wrong
char Celula::virtual simbolo(void) const; virtual {
   return 'X';
}

Sorry for the double post.
I tried to change the syntax according to an example i saw on internet (http://codesyntax.netfirms.com/lang-cpp.htm )

virtual char Celula:: simbolo(void) const{
   return 'X';
}

but i receive error 74 virtual outside class declaration [Celula.o] Error 1
I was thinking i should include the code on the .hpp file for this to work

So you basically want to define your function that is on the class Celula, called simbolo that returns a constant virtual char value.

class definition is on a header file , also the declaration of your method
virtual char simbolo(void) const;

definition of the function/method inside class Celula goes to .cpp

virtual char Celula::simbolo( ) const
{
      return 'X';
}
   

I think you getting that error because you are declaring the fucntion/method again outside the class. You only want to define that method saying that is part of class Celula and that returns a constant virtual char.

May be try to declare and define the virtual on the class (.h)

I hope this helped...

Inside the class: virtual char simbolo() const;
outside the class:

char Celula::simbolo() const  // no virtual specifier, it isn't needed here
{
   return 'X';
}
