    float qty, amount;

  public:

    product(const product&);

    product(float = 0);

    static float getprice();

    static float gettotat();

    static float getamount();

    void setprice(float pr);

    int equal();

    void input();

    void print();

};

 

float product::price=2000;

float product::total=0;

 

product::product(const product &qty){

  this->qty=qty.qty;

  this->amount=qty.amount;

  total+=this->amount;

}

float product::product(float qty)

:qty(qty)

{

  amount=qty*price;

  total+=amount;

}

int product::equal(product other){

  if(this->qty==other.qty && this->amount==other.amount)

    return 1;

  else

    return 0;

}

float product::getamount(){

  return amount;

}

float product::getprice(){

  return price;

}

float product::gettotat(){

  return total;

}

product::setprice(3800){

  return price;
