operator = overload help

[daianahoney]

Hello forum. I cant figure out how to overload the '+' operator or maybe theres another error? Im posting from phone so excuse the slopyness. Thanks!

#include <iostream>
#include <string.h>
#include <ctype.h>
using namespace std;

class Ferma
{
public:
    static int nr_rate;
    static int nr_gaini;
    static int nr_porci;
    static int nr_vaci;
    virtual void afisare()
    {
        cout<<"Ferma:\n";
    }
private:
    int id;
    string animal;
};

int Ferma::nr_rate=0;
int Ferma::nr_gaini=0;
int Ferma::nr_vaci=0;
int Ferma::nr_porci=0;
class Pasari:public Ferma
{
public:

    Pasari(string s):animal(s)
    {
        if(s=="rata")
        {
            ++nr_rate;
            id=nr_rate;
            cout<<"Tocmai am creeat rata"<<id<<"!"<<endl;
        }
        else if(s=="gaina")
        {
            ++nr_gaini;
            id=nr_gaini;
            cout<<"Tocmai am creeat gaina"<<id<<"!"<<endl;
        }
    }

    void afisare()
    {
        cout<<"animalul este "<<animal<<id<<endl;

    }
    Ferma

Where is the code for the overloaded operator? Please make some attempt at that code and post back.

So the problem is at the assignement in main(). Sorry for the previous post. I know the design is a mess so tips are welcomed.

#include <iostream>
#include <string.h>
#include <ctype.h>
using namespace std;

    {
        cout<<"Ferma:\n";
    }
private:
    int id;
    string animal;
};

int Ferma::nr_rate=0;
int Ferma::nr_gaini=0;

Solved. Thanks, had to use a vector of pointers to base class so i could use polymorphism.
