Using conditional statement, write a C$++$ program that will simulate an Internet Service Provider, ISP, that calculates a customer$$s monthly bill. The ISP company has three different subscription packages for its customers:

Package

Monthly cost

Extra charge

Basic

$$9\mathrm{.}99$ per month for $5$ hours of streaming

For $6$ to $10$ hours, extra charge of $$5\mathrm{.}99$

For $11$ to $20$ hours, extra charge of $$9\mathrm{.}99$

For $21$ hours and up$,$ extra charge of $ $15\mathrm{.}99$

Plus

$$14\mathrm{.}99$ per month for $20$ hours of streaming

For $21$ to $30$ hours, extra charge of $$7\mathrm{.}99$

For $31$ hours and up$,$ extra charge of $ $12\mathrm{.}99$

Elite

$$29\mathrm{.}99$ per month for $30$ hours of streaming

For $31$ to $40$ hours, extra charge of $$8\mathrm{.}99$

For $41$ hours and up$,$ extra charge of $ $10\mathrm{.}99$

The program should ask the user to enter a customer name, which package the customer has purchased, and how many hours were used. The total number of hours must be between $1$ and $720$ hours. Any other hours, the program will not make the calculation and prompt a receipt as ZERO purchases.

At the end of the program, the program will create a bill with the following information:

$----------------$ INTERNET SERVICE CHARGE $-------------$

Customer name $\_\_\_\_\_\_\_$

Package $\_\_\_\_\_\_\_$

Total hours used $\_\_\_\_\_\_\_$

Package charge $$\_\_\_\_\_\_$

Extra charge $$\_\_\_\_\_\_$

TOTAL $$\_\_\_\_\_\_$
