Question

C++, any help would be appreciated. Everything I do doesn't want to work. Thanks

Create a linked list program with a .h and a .cpp file. A menu is needed like below and the print list should just print the list. Print order summary, an example is bellow butt a cookie and amount would be great. And Exit is to well exit.

1. Print Ordering Summary

2. Print List

3. Exit

This is what will be in the text file for example and there will be more than that.

Code to help:

struct CookieNode
{
     char cookie_name[COOKIE_NAME_SIZE];

     int num_boxes;

     char customer_name[CUSTOMER_NAME_SIZE];

     CookieNode * next;

};

Order summary example

Cookie Names	Number of Boxes
Carmel Delight	4
Lemonade	1
Shortbread	2
Thin mint	1

Hi,
Creating a full program for this project is too big, and probably out of scope of HomeworkLib answer. As you have asked for help, i will try to help you in short on how you should approach your project..


What you will do is basically:
1. Read the input file data. Then you need to parse the data, so that you get to know what a customer wants.

2. What i see is, it seems, there are some constant number of products, like Carmel Delight, Lemonade etc.
And a customer can order any quantity of any item. What i see from you current struct is, You are creating a node to store only one item and its quantity along with customer info.. 

Why don't you use below structure:

// assuming there are only 4 items
struct CookieNode {
     char cookie_name[4][COOKIE_NAME_SIZE];
     int num_boxes[4];
     float prices[4];
     char customer_name[CUSTOMER_NAME_SIZE];
     CookieNode * next;
};

What above node does is, it stores a customer name, and for all of the items, it stores how much quantity customer wants, and what is the unitprice of each product. In this way, there will be just one node for each customer in the linkedList. And also, it sotres the link to next linkedlist node.


3. As You need to print the order Summary, what you need to do is, traverse the linkedList and keep on calculating the quantity ordered for a product.. 
Like "Carmel Delight" is at index 1, so to find total quantity of "Carmel Delight", we can traverse the list and sum the num_boxes[0] value in each node. Similarly for other items. As you wanted the cost of the items too, that You can do by summing num_boxes[0] * prices[0] on the node. That way you will get total price for "Carmel Delight".


4. you want to print list, that should be straight forward now, as one customer is inside one node only.. So you can visit each node, and based on num_boxes, you can print the details of what that customer wants.

I have tried to answer your question fundamentally, If you want more specific details such as code etc, I would suggest you to please post small questions in separate thread on HomeworkLib. Let me know if it helps, or any issues. Thanks!
