I'm sorry about the bad summary I'm not sure exactly where the problem is. 

%cat generror.cpp
#include <iostream>
using std::cout;
class Fish
{
protected:
    int prot_id;

public:
  Fish(int id):prot_id(id+2)
    {}
};

class GoldFish : public Fish
{
public:
    int getprot_id()
    {
        return prot_id;
    }
    GoldFish(int id):Fish(id){}
};


int main()
{
    GoldFish GF(33);
    cout << "\n" << GF.getprot_id();

    return 1;
}
