I will give the what you need as long as you take the work Title: Shopping Cart Management System (Part 2)
This is a continuation of the assignment 3. With the assignment 3, you need to address additional requirements as
described below.
Additional requirements
(1) Supporting additional commands
a.
Your program needs to support two commands “remove” and “adjust” additionally. The “remove”
command is used to eliminate item(s) from the shopping cart. The “adjust” command is used to
change the quantify information of the user selected item.
b.
Overall, you program must support the four commands as (1) add, (2) remove, (3) adjust, (4) print,
and (5) quit.
(2) Exception handling
a.
Handling commands when they were entered as uppercase, lowercase, or mixed characters (for
instance, “Add” and “add” need to be recognized as the same command). In the previous assignment
(i.e., Assignment 3), you were asked to use if … else statement. Instead, in this assignment, you are
required to use match expression.
b.
Handling incorrectly entered inputs. When the user enters string (or characters) for the quantity or
unit price, a warning message needs to be printed out. Then, ask correct information again.
Enter a command (add, remove, adjust, print, quit): Add
Enter new item’s name: shoes
Enter new item’s quantity: ten
–>The quantity has been entered incorrectly!
Enter new item’s quantity: 5
Enter new item’s unit price: three hundred
–>The unit price has been entered incorrectly!
Enter new item’s unit price: 300.00
PROCESSING COMMAND(S)
For any invalid commands, a notification message should be printed on screen.
