Question
Page of 4 ZOOM+ NOTE: You don't have to include a header and comments in your program. NOTE: Have all your code in a single file. Structure of your code should be as follows 1. Class Employee Interface 2. Class Employee Implementation (even though they will be in the same file, you will still need to include class scope resolution for functions) 3. Class EmployeeList Interface 4. Class Employee List Implementation (even though they will be in the same file, you will still need to include class scope resolution for functions) 5. Main function. Write a payroll program that would allow user to compute the gross pay salary of hourly based employee, average salary in the company, and find employees with highest and lowest salaries. Employee salaries should be computed using hourly rate with consideration of number of hours worked per week. Regular time: 40 hours or less per week, pay rate hourly pay. Overtime: more than 40 hours per week, pay rte # 1.5 of hourly pay. INPUT: Your program should read employee information from a text file provided on Midterm Lab Exam assignment page. PROCESS: For each line in the file, your program should . calculate employee salary . create an instance of the Employee class with employee name and salary add that Employee to the EmployeeList After input file is processed your program should · find employee with highest salary . find employee with lowest salary compute average salary for the company. OUTPUT: List of employees: name and salary (formatted) .Explanation / Answer
