I keep getting an error about m_pHead in printStoresInfo(); function in the cpp file.

CustomerList.h

#pragma once;

#include #include "Store.h"

class CustomerList {

public: Store *m_pHead; CustomerList(); ~CustomerList(); bool addStore(Store *s); Store *removeStore(int ID); Store *getStore(int ID); bool updateStore(int ID, char *name, char *addr, char *city, char *st, char *zip); void printStoresInfo();

};

return true;

}

else { Store *retStore = new Store; *retStore = *temp; retStore->m_pNext = NULL; return retStore; }

} bool CustomerList::updateStore(int ID, char *name, char *addr, char *city, char *st, char *zip) { return false; }
