In the above program make the necessary changes so that a new struct, date, is defined for the expiration date of the product. Thus, an expiration date, day, month, and year, will be associated with each node. Use the following expiration dates for each item: Rolls 08/10/2003 Jam 09/12/2003 Tea 01/01/2010 #include #include #include using namespace std; struct Node { string item; int count; Node *link; }; typedef Node* NodePtr; void head_insert(NodePtr& head, string an_item, int a_number); void show_list(NodePtr& head); int main() { NodePtr head = NULL; head_insert(head, "Tea", 2); head_insert(head, "Jam", 3); head_insert(head, "Rolls", 10); show_list(head); return 0; } void head_insert(NodePtr& head, string an_item, int a_number) { NodePtr temp_ptr; temp_ptr = new Node; temp_ptr-> item = an_item; temp_ptr-> count = a_number; temp_ptr->link = head; head = temp_ptr; } void show_list(NodePtr& head) { NodePtr here = head; while (here != NULL) { cout << here-> item << "\t"; cout << here-> count << endl; here = here->link; } }
Exercise 15.1
In the above program make the necessary changes so that a new struct, date, is defined for the expiration date of the
product. Thus, an expiration date, day, month, and year, will be associated with each node. Use the following expiration
dates for each item:
Rolls 08/10/2003
Jam 09/12/2003
Tea 01/01/2010
#include <iostream>
#include <cstddef>
#include <string>
using namespace std;
struct Node
{
string item;
int count;
Node *link;
};
typedef Node* NodePtr;
void head_insert(NodePtr& head, string an_item, int a_number);
void show_list(NodePtr& head);
int main()
{
NodePtr head = NULL;
head_insert(head, "Tea", 2);
head_insert(head, "Jam", 3);
head_insert(head, "Rolls", 10);
show_list(head);
return 0;
}
void head_insert(NodePtr& head, string an_item, int a_number)
{
NodePtr temp_ptr;
temp_ptr = new Node;
temp_ptr-> item = an_item;
temp_ptr-> count = a_number;
temp_ptr->link = head;
head = temp_ptr;
}
void show_list(NodePtr& head)
{
NodePtr here = head;
while (here != NULL)
{
cout << here-> item << "\t";
cout << here-> count << endl;
here = here->link;
}
}
