Question

help Rewriting the Programming ( will rate )

1.using arrays, and user defined simple data types to hold customer data.

2.Your input will come from a text file of at least 15 customers

3. 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.

code

#include <iostream>

#include <iomanip>

using namespace std;

//Named constants – residential customers

const double RES_BILL_PROC_FEES = 4.50;

const double RES_BASIC_SERV_COST = 20.50;

const double RES_COST_PREM_CHANNEL = 7.50;

//Named constants – business customers

const double BUS_BILL_PROC_FEES = 15.00;

const double BUS_BASIC_SERV_COST = 75.00;

const double BUS_BASIC_CONN_COST = 5.00;

const double BUS_COST_PREM_CHANNEL = 50.00;

int main()

{

//Variable declaration

int accountNumber;

char customerType;

int numOfPremChannels;

int numOfBasicServConn;

double amountDue;

cout << fixed << showpoint;

cout << setprecision(2);

cout << "This program computes a cable "

<< "bill." << endl;

cout << "Enter account number (an integer): ";

cin >> accountNumber;

cout << endl;

cout << endl;

switch (customerType)

case 'r':

case 'R':

cout << "Enter the number"

<< " of premium channels: ";

cin >> numOfPremChannels;

cout << endl;

amountDue = RES_BILL_PROC_FEES

+ RES_BASIC_SERV_COST

+ numOfPremChannels *

RES_COST_PREM_CHANNEL;

cout << "Account number: "

<< accountNumber

<< endl;

cout << "Amount due: $"

<< amountDue

<< endl;

break;

case 'b':

case 'B':

cout << "Enter the number of basic "

<< "service connections: ";

cin >> numOfBasicServConn;

cout << endl;

cout << "Enter the number"

<< " of premium channels: ";

cin >> numOfPremChannels;

cout << endl;

if (numOfBasicServConn<= 10)

amountDue = BUS_BILL_PROC_FEES

+ BUS_BASIC_SERV_COST

+ numOfPremChannels *

BUS_COST_PREM_CHANNEL;

else

amountDue = BUS_BILL_PROC_FEES

+ BUS_BASIC_SERV_COST

+ (numOfBasicServConn - 10) *

BUS_BASIC_CONN_COST

+ numOfPremChannels *

BUS_COST_PREM_CHANNEL;

cout << "Account number: "

<< accountNumber << endl;

cout << "Amount due: $" << amountDue

<< endl;

break;

default:

cout << "Invalid customer type." << endl;

}//end switch

return 0;

}
