Question

Write a program. Body Mass Index using the following functions:

Develop a BMI (Body Mass Index) program with the following functions: 1. All I/O statements must be in GUI style 2. Development a BMI class with a default constructor, a constructor for person?s name, weight, height 3. A main class to demo the BMI class 4. Display programmer?s name (your name), the function of the program with BMI formula 5. Accept person?s name, weight, height 6. Verify I/P data, notify user of invalid data entered and allow to reenter. 7. Calculate the BMI value 8. Display these information: name, weight, height and BMI value with 2 decimal points (example: 29.95) 9. Give comment about her/his BMI such as: Underweight, normal weight, overweight, and obese 10. Save all data including comment of the BMI value in an array 11. Loop back for more BMI and give chance to end the loop 12. At end display the following information: - Total number of BMI calculated - Average BMI value - Lowest and highest BMI values 13. Allow user to look up BMI values in a loop with end of operation function. Draw and label these quantities in the figure below.
