Write a program in C++ (input/output) 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".

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 employees 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.
