reading data from text file
I'm writing this program where I write data to s file and the read it from it. Here is my code:
Code:
#include<iostream>
#include<string>
#include<iomanip>
#include<fstream> //for using files
using namespace std;
int main(){
int hours;
double bill = 0; //total charge
char package;
string name, line;
ofstream output_file; //to write bill
ifstream input_file; //to display bill
cout << "welcome to your bill.\nPlease enter your first name.\n";
cout << ">>";
cin >> name;
cout << "select the internet package you have:\n";
cout << "Pacakage A\nPackage B\nPackage C\n";
cin >> package;
package = toupper(package);
cout << "enter the amount of hours you used the service: ";
cin >> hours;
switch(package){
case 'A':
bill = hours <= 10? 9.95 : (9.5 + (2*(hours - 10))); //calculate price
break;
case 'B':
bill = hours <= 20? 14.95 : (14.95 + (1 * (hours - 20)));
break;
case 'C':
bill = 19.95;
break;
default :
cout<< "you entered an invalid choice";
}
//write data to file
output_file.open("bill.txt");
output_file << name << "\n";
output_file << "you have package " << package << "\n";
output_file << "you have used " << hours << " hours this month\n";
output_file <<"your bill is " << bill << " dollars.\n";
output_file.close();
input_file.open("bill.txt");
getline(input_file, line, '.');
cout << line << endl;
input_file.close();
return 0;
}
the problem I have is that it doesn't read the word "dollars" even though is before the '.'
sample output
Code:
welcome to your bill.
Please enter your first name.
>>peter
select the internet package you have:
Pacakage A
Package B
Package C
b
enter the amount of hours you used the service: 5
peter
you have package B
you have used 5 hours this month
your bill is 14
Also how can I display the correct amount. When I look at the text file everything seems to be written to it.
