You will create a program that displays amount of a cable bill. The Amount is based on the type of customer, as shown in the figure. For a residential customer, the user will need to enter the number of premium channels only. For a business customer, the user will need to enter the number of connections and the number of premium channels. Also enter appropraite comments and any additional instructions in your c++ program. Test the program appropriately before submission.
For resedential customers:
Processing fee: $4.50
Basic service fee: $30
Premium channels: $5 per channel
For business customers:
Processing fee: $16.50
Basic service fee: $80 for the first 5 connections, $4 for each additional connection
Premium channels: $50 per channel for any number of connections
