Question

C++

• Write a program to create a linked list which stores the details of employees(Employee number, employee name, rate, hours worked). Create a menu to manage the emoployee data.

MENU

1. ADD EMPLOYEE DETAILS

2. DELETE EMPLOYEE

3. SEARCH EMPLOYEE

4. PRINT EMPLOYEE PAYROLL

5. EXIT

• When the user selected option #4 the program should print the following pay report for each employee:

EmpNo.     Name      Rate    Hours    Regular Pay      Overtime Pay     Gross Pay

• Any hours worked above 40 hours are paid at time and a half. Additionally, the program should display the totals of regular, overtime and gross pay columns.
