  flag = Bob.checkout(&Master._Inv);
  flag = Arjun.checkout(&Master._Inv);
  Master.summary();*/



  system("pause");

}

here is PART OF my header file:

class Inventory;
class Customer {
  public:
    Customer(string n, int c, double b );
    ~Customer() { _Cart.clear(); };
    bool addCart( string name, int q, Inventory* inv );
    bool removeCart( Food f, int q, Inventory* inv );
    void report(); 
    bool checkout(Inventory* inv); 
  protected:
    string name;
    int card;
    double balance;
    CreditCard _CC(int c,double b);
    vector<Food> _Cart;
};


The error i am getting is: cannot convert parameter 3 from 'std::vector<_Ty> *' to 'Inventory *'
1>          with
1>          [
1>              _Ty=Food
1>          ]
1>          Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

I could appreciate the help. so the error is showing when i am using &Master._Inv. _Inv is a vector of food i declared somewhere else in my header but have not included. However the problem is with the pointer &Master.... i also tried *Master._Inv but did not work either.

  • You're using [reserved identifiers](http://stackoverflow.com/questions/228783/what-are-the-rules-about-using-an-underscore-in-a-c-identifier). You should get out of that habit. Other nitpicks are `using namespace std;`, `system("PAUSE");`, and the fact that `Customer`'s destructor is completely pointless since the vector is about to die anyway. – chris Aug 04 '12 at 04:22
  • Does your compiler print some line number for the error? If not did you removed line by line until you identified the errornous line? – harper Aug 04 '12 at 04:26

The error message is pretty straightforward. addCart, removeCart, and checkout all take a pointer to Inventory as a parameter. But your argument &Master._Inv is a pointer to a std::vector<Food>. Maybe you meant just &Master?

The third parameter to Customer::addCart() is a pointer to an Inventory object. Try passing it &Master.
