fixing project

i have my code for the project and it has one problem only 

the problem in the print function 

first of all, the following should be a pointer in Customer class:

Product *item; Now, the Print function, in general, should look something like this: void Print(Customer *h){while(h){//here you should print all the details of a customerProduct * p = h->item;while(p){//here you should print a product’s details//move to the next product as below:p=p->next;}//move to the next customer as below:h=h->next;}}

#include

using namespace std;
//Product class
class Product {
public:
string name;
float price;
Product *next;
};
//Customer class
class Customer

string lastname;
string type;
Customer *next;
Product item;
