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: (3 marks) Task 1: Declare a structure named Item, with the following members: 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 (c).

(10.5 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 determine the items' names and cost based on the information given in Table 1. Cost (RM) 11.5 Code M101 B202 C303 F404 Table 1 Name Double Mushroom Double BBQ Beef Grilled Chicken Fish'n Crisp 10.0 12.5 15.0 d) The function should also calculate the sale price for each item by adding 30% (markup percentage) to the cost of the item Example, if an item costs RM50 to produce, and you want to apply a mark-up of 25%, you need to multiply 50 by 1.25. The sale price would be RM62.50. Task 4: Write a function named displayOutput. (10.5 marks) a) This is a non-retuming 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 code, name, cost, sale price, number of items sold, and profit. The formula for calculating item profit is as follows: Item profit = Number of items sold (Sale price - Cost) 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.
