Rewrite the Programming Example page 236 in chapter 4 ( Cable Company Billing ). Expected Program and Design: 1. Write a pseudo code before starting your program ( do not use SWITCH, replace it with IF structures ) 1.1 Draw a flowchart for your program based on your pseudo code 2. Identify your constants 3. Your input will come from a text file of at least 15 customers 3.1 Input file format - customerType accountNumber premiumChannels ( i.e residential example: R12345 5 , business example B12345 16 8 ) 4. Precision should be two decimal places 5. Calculate the running average for residential and business customer spending 6. Print all customer's bill to a single file and the end of the file you should have the average summary for each customer type. 6.1 Pay attention to details when you formatting your output

Note: Use all chapter concepts and make your final as a true representation of what we have learned this semester. Turn in program design ( pseudo code and/or flow chart ) input file output file .cpp file of your program ( make sure you include your header and comment your code ) Extra credit Implement your program using arrays, covered in chapter 8, and user defined simple data types to hold customer data.

} How would I implement arrays? And is this correct? Does this code effeciently use Input/output Control Structures User Defined Functions User Defined simple data type/namepsaces/strings

I feel like it does seem to work, but I'm stuck on how to implement this into an array
