Instructions

Write a program that reads data from a file specified by the user at runtime $($i$.$e$.$ your program should accept the filename as user input$)$ and stores the output in the file Ch$3\_$Ex$5$Output.dat. To test your program, use the Ch$3\_$Ex$5$Data.txt file.

Your program will not pass all checks if it does not accept a filename as input from the user.

For each employee, the data must be output in the following form: firstName lastName updatedSalary.

Format the output of decimal numberspito two decimal places.

Since your program handles currency, make sure to use a data type that can store decimals.
