Question

My question is how to pull data from the file given (data.txt) word by word to get the desired output? I was thinking "getline" , but that pulls the whole 1st line right?

Once I get the data from the file I am good to go. I know the basics of pulling data from a file normally, just not how to do it word by word and insert each of those words into different parts of the code.

I don't want a full solution, I am trying to learn it, but my textbook doesn't put both of these concepts together, so I am totally lost.

Program description (Phone Bill Calculator) Write a complete C++ program for a mobile phone operator to compute the monthly phone bill. Mobile phone operator provide two types of service: Regular (r) and Premium (p) The company has different bill plan for these two types of customers, see the following: Phone Plan for Premium Service Cost Monthly base payment $59.99 First 500 minutes of DayTime talk $0.00 (free) First 100 minutes of NighTime talk $0.00 (free) Remaining DayTime talk minutes $0.30/per minute Remaining DayTime talk minutes $0.45/per minute Phone Plan for Regular Service Cost Monthly base payment $24.99 $0.00 (free) First 250 minutes of AllTime talk Remaining AllTime talk minutes $0.25/per minute In this assignment, you will need to develop a program that reads customer phone usage information from a text file named data.txt, and produces the phone bill per the criteria given above The format of the data in the file is: service Type accountNum DayTimeMinutes NightTimeMinutes The serviceType field is either p (for Premium service) or r (for Regular service) accountNum is a unique customer identification number

using namespace std;

   ifstream inFile ("1.txt");

   }
   inFile.close();
   }

   else cout << "Unable to open file";

return 0;

}

/*
data.txt
r 125555 223 674
p 678953 334 34

output:

Account Number:   125555
Service Type:   Regular
Total Minutes used:   897
Monthly base payment: $24.99
Charges on minutes: $161.75
Total Amount Due: $186.74

Account Number:   678953
Service Type:   Premium
Total Minutes used:   368
Monthly base payment: $59.99
Charges on minutes: $0
Total Amount Due: $59.99
