Function Search

[vijaySone]

can you help me guys on how to edit the sample codes based on the requested things below? Thankss ☺☺
#include <iostream>
#include <cstddef>
#include <string>
using namespace std;
struct Node
{
string item;
int count;
Node *link;
};
typedef Node* NodePtr;
NodePtr search(NodePtr head, string an_item);
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);
cout << "List contains:" << endl;
show_list(head);
string target;
cout << "Enter an item to search for" << endl;
cin >> target;
NodePtr result = search(head, target);
if (result == NULL)
cout << target << " is not on the list." << endl;
else
cout << target << " is on the list." << endl;
return 0;
}
NodePtr search(NodePtr head, string target)
{
// Point to the head node
NodePtr here = head;
// If the list is empty nothing to search
if (here == NULL)
{
return NULL;
}
// Search for the item
else
{
// while you have still items and you haven't found the target yet
while (here-> item != target && here->link != NULL)
here = here->link;
// Found the target, return the pointer at that location
if (here-> item == target)
return here;
// Search unsuccessful, return Null
else
return NULL;
}
}
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 << endl;
here = here ->link;
}
}


Modify the above program to include the expiration date, then give the users a search choice. Provide
two search options:
1) item, the way it is done in the program, and
2) expiration date

So what have you thought about (other than posting code online).

I mean, if you really got this far all by yourself, adding "expiration date" would be simple.

But you asking means either you "found" the code, or you were "given" the code.

Either way, show some effort on your part.

You're not going to be getting a ready made answer you can run back to teacher with.
