The Ministry of Health Malaysia is responsible for providing health services to help citizens of Malaysia in sustaining a certain level of health that allows them to lead a productive lifestyle. Assume that you are a programmer working for ministry. You have been asked to write a CH program to facilitate the ministry to develop a health care system for Body Mass Index (BMI) Calculator module. The module is to measure body fat based on height in meter and weight in kilogram that applies to adult men and women. There are seven (7) tasks already listed to complete the program. You are given a partial complete of C++ program Question2.cpp) and an input data file (input.txt). Complete the source code according to the tasks given as follows; TASK 1: Complete the definition of function readFile. This function reads the patient data inputs from the provided input text file named input.txt. The patient data consists of patient's name along with their weight in kilogram and height in centimeter. The read data are then stored into arrays accordingly. Input Validation: Please make sure that the program will only continue reading the file if it is successfully opened, otherwise print the error message and exit the program TASK 2: Complete the definition of function convertMeter, which converts patient's height in centimeter to meter. The formula to convert is as follows: height (meter) - height (cm) / 100 TASK 3: Complete the definition of function calculateBMI, which calculates the patient's Body Mass Index (BMI) based on weight in kilogram and height in meter from two arrays correspondingly and puts the results into another array. The formula to calculate BMI is as follows: BMI = weight (kg)/(height (m) * height(m)) TASK 4: Complete the definition of function average. This function calculates the average value of array elements, which calculates the average weight of patients. TASK 5: Using all functions defined above, write a function call: (a) to read file from the input file, (b) to convert centimeter to meter, (c) to calculate BMI and (d) to calculate average weight of patients. TASK 6: Print the list of patient's names along with their weight in kilogram (kg), height in meter (m), and the calculated BMI to the output file named output.txt as shown in Figure 2.1. Note: You should use proper output formatting (align output to the left and number formatting shows two (2) decimal places).

Note: You should use proper output formatting (number formatting for average shows one decimal place) Writing to the output file... Number of patients . 6 Average weight : 57.9 Figure 2.2: Sample output in program screen
