Problem 5. (30 Points) Write a program that reads employee work data from a text file employee.txt), and then calculates payroll information based on this file and store them into a new text file called payroll.txt. The employee. txt file contains one line of text for each employee. Each line consists of the following data (delimited by tabs): employee's name, employee's hourly wage rate, hours worked Monday, hours worked Tuesday, hours worked Wednesday, hours worked Thursday, hours worked Friday employee.txt Smith 10 8 8 8 8 10 Manny 12.50 4.75 3.3 2.2 Miller 20 6.5 9111 Baker 15 7.5 9 40 2 Sammy 11.50 4.5 9 7 3 2 Choi 6,50 20 20 2,5 4 4 payroll.txt Name Hours Pay Smith 42 $420.00 Manny 21.5 $268.75 Miller 18.5 $370.00 Baker 22.5 $337.50 Sammy 25.5 $293.25 Chai 50.5 $328 25 The employee Smith makes $10 per hour, and worked 8 hours on Monday, 8 on Tuesday, 8 on Wednesday, 8 on Thursday, and 10 on Friday.
