Write a complete C++ program. The program uses various types of structured data developed to calculate the profit of each item, the total amount of profit, and the highest profit. The program should perform the following tasks: Task 1: Declare a structure named Item, with the following members: (3 marks) a) Code b) Name c) Cost d) Sale price e) Number of items sold f) Profit Task 2: Write a function named readInput. (10 marks) a) It receives an array of Item of type struct. b) The function should read data from the given input text file named input.txt. The file contains items codes and the number of items sold. Figure 1 shows an example of data that can be used to test the program. c) Assuming you do not know, the number of items. Calculate the number of items sold based on the number of item records found in the input file. d) The function should return the number of items calculated in (e).

(17 marks) a) This is a non-returning function. b) It takes an array of Item of type struct and the number of items calculated in Task 2 as input parameters. c) The function should display items' names and total profit for each item. 3 d) The function should also calculate and display the total amount of profit for all items and the highest profit. e) Figure 3 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. ITEM NAME Double Mushroom Double BBQ Beef Grilled Chicken Fish'n Crisp TOTAL PROFIT (RM) 151.80 309.06 218.40 91.88 The total amount of profit = RM 527.46 Highest profit - RM 309.06 Figure 3: Expected output for Task 5 Task 6: Write a main function to perform the following tasks: (5 marks) a) Declare one-dimensional array variable with 50 elements for a structure type Item b) The function may need to call the functions that are defined in the previous task to produce the output as shown in Figure 4. Note: Please use proper output formatting. c) Figure 4 shows the complete output that will be displayed on the screen based on the data in the input file "input.txt" shown in Figure 1.
