Question

How to make a flow chart out of this???

To compute the rates you have the following established: 1. Regular service - $6.00 plus first 50 minutes free. Charges for over 50 minutes are $0.20 per minute. 2. Premium service - $15.00 plus: a. For calls made from 6:00am to 6:00pm, the first 75 minutes are free; charges for over 75 minutes are $0.10 per minute. b. For calls made from 6:00pm to 6:00am, the first 100 minutes are free; charges for over 100 minutes are $0.05 per minutes. Task Your task at the moment is to calculate and print out the bill for your customers. Your program should: 1. prompt the user to enter an account number, 2. a service code (type char), a. A service code of r or R means regular service b. A service code of p or P means premium service c. Treat any other character as an error 3. the number of minutes the service was used. 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. Concepts to follow: 1. Assign values to all constant variables that are associated with charges and number of minutes provided in the problem description. 2. The only information the user enters are: account number, type of service, minutes used, and day/night time minutes used based on the plan they have. 3. Remember you are dealing with money therefore should only have 2 decimal places. 4. You must use both a switch statement AND if/else, if/else if’s, or if’s as you see fit. 5. Keep in mind to check for input validation. If validation is incorrect you should have an error message and “kill” your program. 6. Do not use loops

// Cellphone use

// cout<< service <<endl;;
if (service == 'r' || service == 'R')
regular();

}
float premium()
{

cout<< "How many minutes were used during the day? ";

cout<< "How many minutes were used during the night? ";
cin >>night_min;
if (day_min > 75)
{
amount_due = ((day_min - 75) * .10)+ 15.00;
}
if (night_min > 100)
{
amount_due = ((day_min - 100) * .05)+ 15.00;
}
amount_due = amount_due + 15.00;
cout<< fixed << showpoint << setprecision(2);
cout<< "Amount due: $" << amount_due << endl;
cout<< "Account number: "<< account_number <<endl;
cout<< "Service type: "<< service << endl;
cout<< "Minutes used: "<< (day_min+night_min) <<endl;

return 0;
}
float regular ()
{
cout<< "How many minutes were used? ";
cin >> minutes;
if (minutes <= 50.00)
{
amount_due = 6.00;
cout<< fixed << showpoint << setprecision(2);
cout<< "Amount due: $" << amount_due << endl;
cout<< "Account number: "<< account_number <<endl;
cout<< "Service type: "<< service << endl;
cout<< "Minutes used: "<< minutes <<endl;

}
else
{
amount_due = ((minutes -50.00) * 0.20);
cout<< setw(2) << showpoint << setprecision(3)<< "Amount due: $"<< amount_due << endl;
cout<< "Account number: "<< account_number <<endl;
cout<< "Service type: "<< service << endl;
cout<< "Minutes used: "<< minutes <<endl;
}
getch();
return 0;

}
