Question

The instructions say the following:

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 Ch3_Ex5Output.dat. To test your program, use the Ch3_Ex5Data.txt file.

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

Here are the steps you must follow:

Ask the user for the filename.
Read their response and save it in a variable.
Instead of opening "Ch3_Ex5Data.txt" you will use the variable that you stored the filename in and open that file.

So if a user enters myFile.txt, you would store that in a variable called inFileName and use inFileName when opening the file instead of "Ch3_Ex5Data.txt". If these instructions seem vague to you, you have not understood the material in the book.

Summary
Three employees in a company are up for a special pay increase. You are
given a file, say Ch3_Ex5Data.txt, with the following data:
Miller Andrew 65789.87 5
Green Sheila 75892.56 6
Sethi Amit 74900.50 6.1
Each input line consists of an employee's last name, first name, current
salary, and percent pay increase.
For example, in the first input line, the last name of the employee is Miller,
the first name is Andrew, the current salary is 65789.87, and the pay
increase is 5%.
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 Ch3_Ex5Output.dat. To test your program, use the
Ch3_Ex5Data.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 numbers to two decimal places.
Since your program handles currency, make sure to use a data type that
can store decimals.
