Reading a Second Variable from a file

I'm trying to get information from a file and perform calculations with it, but the second float value is not reading properly.

#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>
using namespace std;
int main()
{       
    string fullName;
    float payRate, hoursWorked;
    int regularHours = 35;
    float grossPay, overtimePay, totalPay;
    
    //Open data file Employee
    ifstream Employeer("Employee.dat");
    
    //Header - 2 lines! Note that the width is 11 instead of 10
    //to account for the '$' in the output.
    cout << left << setw(18) << "Full" << setw(9) << "Hours" <<
         setw(10) << "Pay" << setw(11) << "Gross" << setw(11)
         << "Overtime" << setw(11) << "Total" << endl;
    cout << left << setw(18) << "Name" << setw(9) << "Worked" <<
         setw(11) << "Rate" << setw(11) << "Pay" << setw(11)
         << "Pay" << setw(11) << "Pay" << endl;

    //Read
    getline(Employeer, fullName, '~');   
    Employeer >> hoursWorked >> payRate;

    
    //Calculations
    grossPay = regularHours * payRate;
    
    if(hoursWorked - regularHours > 0)
    {
        overtimePay = (hoursWorked - regularHours) * (payRate * 1.5);
    }
    else
    {
        overtimePay = 0;
    }
    
    totalPay = grossPay + overtimePay;
    
    //Display
    cout << left << setw(18) << fullName << setw(9) << hoursWorked << "$" << fixed
         << setprecision(2) << setw(10) << payRate << "$" << fixed << setprecision(2)
         << setw(10) << grossPay << "$" << fixed << setprecision(2) << setw(10)
         << overtimePay << "$" << fixed << setprecision(2) << setw(10)
         << totalPay << endl;
         
         Employeer.close();
         
         cin.get();
         cin.ignore();
         return 0;
         }


When I try to run it all I get is
Full              Hours    Pay       Gross      Overtime   Total
Name              Worked   Rate       Pay        Pay        Pay

I'm taking a guess, '~' is used as a delimiter throughout the file? If so, then you need to extract it between extracting hoursWorked and payRate.

It would help to see the formatting of the file.

Yes, '~' is.

Here is the file:
callaway~6~40
hanson~6.5~48
goldberg~8~35
stallman~8.5~50
Lowest0ne (1536)
The quick and dirty method is to declare a char junk; and extract that second '~' before payRate:
1
2
 
    getline(Employeer, fullName, '~');   
    Employeer >> hoursWorked >> junk >>payRate;


Though I wonder if that '\n' after "40" is going to make "hanson", "\nhanson". Might be wise to use cin.get() after extracting payRate.

A more flexible way to do this would be to extract the entire line as one string, and then use the delimiter to parse that.
