using namespace std;




class List
{
public:
List(); //default constructor
//List(int ID, char *LN, char *FN, char *T, int Q, int A); //constructor
~List(); //deconstructor
void Display();
void SearchID ();
void SearchName();


private:
int IdNumber;
char LastName;
char *FirstName;
char *Type;
int Quantity;
int Amount;
};
#endif






#include "List.h"
