Program Algorithm
A program algorithm for this shop.
The program or programs must include appropriate prompts for the entry of data; data must be validated on entry. Error messages and other output need to be set out clearly and understandably. All arrays, variables, constants and other identifiers must have meaningful names.
Complete these three tasks.
Task 1 – Setting up the system. Write a program to: use appropriate data structures to store the item code, description and price information for the mobile devices, SIM cards and accessories; allow the customer to choose a specific phone or tablet; allow phone customers to choose whether the phone will be SIM Free or Pay As You Go; allow the customer to choose a standard or luxury case; allow the customer to choose the chargers required (none, one or both may be purchased); calculate the total price of this transaction; output a list of the items purchased and the total price.
Task 2 – Allow a customer to order multiple mobile devices. Extend Task 1 to: offer the customer the opportunity to purchase an additional mobile device; if required, perform bulleted steps 2 to 7 of Task 1 for each additional mobile device and calculate a running total for the customer; once no further devices are required, output the total the customer will need to pay.
Task 3 – Offering discounts. Extend the program to allow a discount of 10% off the price of every additional phone or tablet purchased. Output the new total the customer will need to pay and the amount of money saved.
