In C++

Rewrite this program (Chapter 4, Problem 1 programming assignment) that calculates and prints the bill for a cellular telephone company as a modular program. The company offers two types of service: regular and premium. Its rates vary, depending on the type of service. The rates are computed as follows:

Regular service: $10.00 plus first 50 minutes are free. Charges for over 50 minutes are $0.20 per minute. 

Premium service: $25.00 plus: 

For calls made from 6:00 a.m. to 6:00 p.m., the first 75 minutes are free; charges for more than 75 minutes are $0.10 per minute. 

For calls made from 6:00 p.m. to 6:00 a.m., the first 100 minutes are free; charges for more than 100 minutes are $0.05 per minute. 

Your program should prompt the user to enter an account number, a service code (type char), and the number of minutes the service was used. A service code of r or R means regular service; a service code of p or P means premium service. Treat any other character as an error. Your program should output the account number, type of service, number of minutes the telephone service was used, and the amount due from the user. For the premium service, the customer may be using the service during the day and the night. Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night.

[This is the metioned code to reform]

#include #include #include using namespace std;

int account_number; float minutes; char service; float amount_due; float day_min; float night_min; float regular(); float premium(); int main() {

cout<< "Please enter your account number: " ; cin >> account_number; cout<< "Do you have Regular service or Premium service (r or p)? "; cin >> service; // cout<< service <

} float premium() {

cout<< "How many minutes were used during the day? "; cin >> day_min; cout<< "How many minutes were used during the night? "; cin >>night_min; if (day_min > 75) { amount_due = ((day_min - 75) * .10)+ 25.00; } if (night_min > 100) { amount_due = ((day_min - 100) * .05)+ 25.00; } amount_due = amount_due + 25.00; cout<< fixed << showpoint << setprecision(2); cout<< "Amount due: $" << amount_due << endl; cout<< "Account number: "<< account_number <

return 0; } float regular () { cout<< "How many minutes were used? "; cin >> minutes; if (minutes <= 50.00) { amount_due = 10.00; cout<< fixed << showpoint << setprecision(2); cout<< "Amount due: $" << amount_due << endl; cout<< "Account number: "<< account_number <

} else { amount_due = ((minutes -50.00) * 0.20); cout<< setw(2) << showpoint << setprecision(3)<< "Amount due: $"<< amount_due << endl; cout<< "Account number: "<< account_number <
