I'm working on a program that reads a series of data records from a file(screenshot of file below) and stores each record in a linked list in ascending order by items number and then prints the report.

I need to edit my program to input a list of item numbers from a file(it will be called purge_items.dat) and from those item numbers listed in the file, I'm to delete the item record if the corresponding item's age is MORE than 5 years old AND the items sold is LESS than 10% if the item_count. However, if the item number is NOT listed in the list from the supplied file, ignore it and go on to the next item number from the purge_items.dat file.

Once that is done, generate a report in a separate file(let's call it "inventory_purge_report.txt") titled "Inventory Purge Report" that looks like the image below

My current is code is below which you can modify

itemPntr->next = Head;

Head = itemPntr;

}

//If the new item number is less than head item number.

//Compares and adds item in middle of list.
