Write a program for Mobile Plus Communications (MPC) Mobile Communications Company that asks customers to select from the list of smart phones in the table above. The Menu will be presented to customers upon entering the MPC.com website. For now, this program will only run on a desktop computer. After all the phones are selected, the customer must then select a Plan from the following Phone Plan Option List:

Phone Plans available after selecting phones from the menu above:

OPTION

SELECTION

Plan A

4 phone Lines or More - $50/Line per month, otherwise a flat fee of $300/month

Plan B

Less than 4 Lines - $70/Line per month, otherwise $50/Line per month

Plan C

Plan with Tablet Line (Any number of Lines) $60/Line per month

If the customer enters any option that is not in the tables above, the program should display “Invalid Option Selected”. You must use the switch statement in your program to solve this problem.

The program should calculate the total cost of the purchase based on the user’s selections and then provide the following output summary.

Number of Phones Purchased for each type of phone

Plan Selected

Number of phone lines activated

Total Cost
