How to loop from input.txt

[lollopes]

Hallo.. I need to write this basic program. And I want it to read my input file from a txt file containing the following:
12345
R
790
29888
X
38116
P
375
982


My code is the following:

#include <iostream>
#include <iomanip>
#include <fstream>


using namespace std;
double charge1;
double charge2;
double charge;


int main()
{
ifstream imputFile;
int accountnumber;
char choice;
int minutes;
int daytimeM;
int eveningtimeM;

cout<<setprecision(2)<<fixed;

imputFile.open("/Users/lorenzopes/Documents/college/C++/example/printingcharge/printingcharge/billingdata.txt");


while(imputFile >> accountnumber)
{




imputFile >>accountnumber;
cout << "Enter your account number: ";
cout<<accountnumber;



imputFile>>choice;
cout<<"Enter your service code: (R/r-regular, P/p-premium): ";
cout<<choice;



switch (choice)
{
case 'R' :
case 'r' :
imputFile>>minutes;
cout<<"How many minutes were used this month? ";
cout<<minutes;

if(minutes<50)

{ charge=0;
cout<<"The monthly charge for account "<<accountnumber<<" is: $"<<charge<<endl;
}


else if(minutes>50)

{
charge=minutes*0.20;
cout<<"The monthly charge for account "<<accountnumber<<" is: $"<<charge<<endl;
}
break;






case 'P':
case 'p':

imputFile>>daytimeM;
cout<<"How many daytime minutes where used this month? ";
cout<<daytimeM;

if(daytimeM < 75)
charge1=0.0;

else if (daytimeM > 75)
charge1=(daytimeM-75)*0.10;

imputFile>>eveningtimeM;
cout<<"How many eveningtime minutes where used this month? ";
cout<<eveningtimeM;

if(eveningtimeM < 100)
charge2=0.00;

else if (eveningtimeM > 100)
charge2=(eveningtimeM-100)*0.05;

charge=25+(charge1+charge2);

cout<<"The monthly charge for account "<<accountnumber<<" is $" <<charge<<endl;
break;


default:

cout<<"** Invalid Service Code – Monthly Bill Not Calculated ** "<<endl;

}
}

}

¿what should the program do?

OK, ¿so?

while(imputFile >> accountnumber)
{
   //¿why so much whitespace?



   imputFile >>accountnumber; //¿how many times will you read the account number?
