When i make the program run, i get the error empty string. There is data in my input file but i cant seem to get it to read it. The program is supposed to read data from file EmployeePayroll.txt (Copy pasted below) and write to EmployeePayStubs.txt with the format that the user encounters when inputting data. How do i make it so that i can read the data as a double and continue to write?

*The salary class was SalaryCalcLoop, i had forgotten to change the name
