Thread: Question about UML.

For this diagram:
http://chorist.mis.ccu.edu.tw/teachi...al/final_5.jpg
Let's talk about the class "S" and "T" only.
Should I write like this:

Code:

class S{
public:
  void setID();
  int getID();
  void printID();
private:
   int i ;
};

class T : public S{
protected:
  int j;
};

or this ?

Code:

class S{
public:
  void setID();
  int getID();
  void printID();
private:
   int i ;
};

class T : public S{
public:
  void setID();     //  <<< different at here
  int getID();
  void printID();
protected:
  int j;
};

The 'i' and 'j' are not important.
The main point is whether I should write the functions repeatedly in the inheritance.

My teacher give me the model answer like the second form. I am wondering because I believe that the first form is correct.

thx.

ref:
'+' = public
'-' = private
'#' = protected
