Write a complete C++ program. The program uses various types of structured data developed to calculate the salary of each employee and the total salary to be paid for each department. The program should perform the following tasks: Task 1: Declare a structure named Employee, with the following members: (3 marks) a) Name b) Department c) Basic salary d) Number of overtime hours worked in one month c) Overtime pay f) Total salary including overtime pay Task 2: Write a function named readinput. (14 marks) a) It receives an array of Employee of type struct. b) The function should read data from the given input file named input.txt. The file contains employees' department, basic salary, number of overtime hours worked in one month, and name. Figure 1 shows an example of data that can be used to test the program. c) Assuming you do not know, the number of employees. Calculate the number of employees available in the company based on the number of employee records found in the input file. d) The function should return the number of employees calculated in (c).

(6 marks) a) It takes the department name as an input parameter. b) The function should return an overtime rate based on the information given in Table 1. 2 Department Quality Production Accounting Engineering Table 1 Overtime Rate (RM per hour) 11.5 10.0 12.5 15.0 Task 4: Write a function named displayOutput. (11 marks) a) This is a non-returning function. b) It takes an array of Employee of type struct and the number of employees calculated in Task 2 as input parameters. c) The function should display employees' names, department, basic salary, number of overtime (OT) hours worked in one month, monthly overtime (OT) pay, and monthly salary. The formula for calculating monthly overtime (OT) pay and monthly salary is as follows: Monthly overtime (OT) pay - Overtime rate Number of overtime hours worked Monthly salary - Monthly overtime pay + Basic salary d) Figure 2 shows an example of the output that will be displayed on the screen based on the data in the input file "input.txt" shown in Figure 1.
