Problem type

The Body Mass Index (BMI) is one of the calculations used by doctors to assess an adult's health. The doctor measures the patient's height (in metres) and weight (in kilograms), then calculates the BMI using the formula:

\displaystyle  BMI = \frac{weight}{height \times height}

Write a program which takes the patient's weight and height as input, calculates the BMI, and displays the corresponding message from the table below.

BMI Category Message

Between 18.5 and 25.0 (inclusive) Normal weight
Less than 18.5 Underweight

    "Write a program which prompts for the patient's height and weight" should be changed. No prompting should be done, and the input order is weight first, then height.
