This is my code and I need help fo finishing this.

Milestone 54

Update Quantity

• Prompts "Item description: " and receives a sub-description from the user dynamically.
• Lists all the iProducts containing the description; if no match is found, it prints "No matches found! "
• After displaying all the matches it asks the user for the SKU of the iProduct that needs updating by prompting "Enter SKU: "
• Then it will search for the SKU to find the index of the iProcuct in the iProduct Pointers.
• If a match is not found it will print "SKU not found! " and exits
• After finding a match it will display a menu for adding or reducing the quantity:

1- Add 2- Reduce 0- Exit > 

• if the user selects exit it will print "Aborted! " and exit.
• If add is selected a fool-proof quantity value is received from 1 up to the maximum amount needed to fulfill the needed quantity using the prompt: "Quantity to add: ". Then the quantity is increased by the entered amount. After increasing quantity, a confirmation message is printed as follows: "X items added!", replacing X with the amount.
• If reduce is selected a fool-proof quantity value is received from 1 up to the quantity on hand using the prompt: "Quantity to Reduce: ". Then the quantity is reduced by the entered amount. After reducing quantity a confirmation message is printed as follows: "X items removed!", replacing X with the amount.
• Selecting Add on an already fulfilled needed quantity should result in issuing the message: "Quantity Needed already fulfilled! "
• Selecting Reduce on a zero quantity should result in issuing the message: "Quaintity on hand is zero! "

Milestone 55

Sort

Sorts the items in the iProduct Pointers array, based on difference between quantity needed and quantity on hand in descending order. When completed it will print "Sort completed! "

Milestone 56

Ship Items

• Make an ofstream for shipping-order-file under the name "shippingOrder.txt".
• Print in the file: "Shipping Order, Date: 9999/99/99 " (9999/99/99 is replaced by the current date)
• Print the table titles as follows:

 ROW | SKU | Description | Have | Need | Price | Expiry -----+-------+-------------------------------------+------+------+---------+----------- 

• In a loop go through all the iProduct Pointers elements and if the quantity needed and quantity on hand of the product is a match print it in the linear format into the file and remove it from the iProduct Pointers array.
• Count the number of printed (shipped) items
• At end close the table by printing:

-----+-------+-------------------------------------+------+------+---------+----------- 

• end the process by printing the number of items shipped on the screen: ""Shipping Order for 999 times saved!"" , 999 is replaced by the number of shipped (removed) items.
