Question

Write a BMI calculator program using loop control, user-defined functions include list, arithmetic and decision control statements with the following conditions :

1) Prompt user to enter the weight in kilogram and height in metres up to 2 decimal places

2) Use the given formula to calculate the Body Mass Index (BMI) and round it to 2 decimal place

BMI = Weight / Height?

3) Create two data list namely, "name list" to store the username and the "bmi list" to store the calculated BMI respectively.

4) With the given BMI category, the program code is able to display the following:

a) Allow user to enter name, weight and height.

b) The username, the BMI value and the category that it falls into.

c) The usernames in the name list and the respective BMI values in the bmi_list.

BMI category are as follows

Less than 18.5

Underweight

18.5 to 24.9

Normal

25 to 29.9

Overweight

30 to 34.9

Obese class

35 to 39.9

Obese class Il

40 to 49.9

Morbid Obese

50 or greater

Obese class IlI
