how to implement functions of derived class

[myoni]

I've 2 classes closedPolynom and Rectangle.
In the header file of Rectangle I'm getting this error:
error C2969: syntax error : ';' : expected member function definition to end with '}'

this is the Rectangle class header file:

#ifndef Rectangle_H
#define Rectangle_H

#include <iostream>
#include "Polynum.h"
using namespace std;

class Rectangle : public closedPolynom
{
public:
	//ctor
	Rectangle(int num) : closedPolynom(num); //<<< here the error 
};
#endif 

and this is Rectangle class implementation code:

#include "Rectangle.h"

Rectangle::Rectangle(int num) : closedPolynom::closedPolynom(num)
{
	n=num;
	sides=new int[num];

	cin>>sides[0];
	sides[2]=sides[0];
	cin>>sides[1];
	sides[3]=sides[1];
}

Don't put the initialization list in the header file. Only put it in the implementation.

[myoni]

what do u mean "the initialization list" ?

I tried this:

Rectangle(int num) : closedPolynom;

and this:

Rectangle(int num) : closedPolynom();

but the error is remaining

[myoni]

anybody know ?

[R0mai]

Rectangle(int num) : closedPolynom() {} //Empty function body

[myoni]

now I'm getting another error (at the implementation:

error C2084: function 'Rectangle::Rectangle(int)' already has a body

[Peter87]

Change
Rectangle(int num) : closedPolynom(num);
to
Rectangle(int num);

[myoni]

thank you
It's better now, but I still have this error:

error C2039: '{ctor}' : is not a member of 'closedPolynom'

this is the code where the error appears:

#include "Triangle.h"

Triangle::Triangle(int num) : closedPolynom::closedPolynom(num)
{
	for (int x=0; x<num; x++)
		cin>>sides[x];
}

[Peter87]

Remove closedPolynom::.

thanx a lot
