Textbook Question

Chapter 4, Problem 8PP

Body Mass Index Program Enhancement

In Programming Problem 6 in Chapter 3, you were asked to create an application that calculates a person’s body mass index (BMI). Recall from that exercise that the BMI is often used to determine whether a person is overweight or underweight for their height. A person’s BMI is calculated with the following formula:

B M I = W e i g h t × 703 ÷ H e i g h t 2

In the formula, weight is measured in pounds and height is measured in inches. Enhance the program so it displays a message indicating whether the person has optimal weight, is underweight, or is overweight. A person’s weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweight.
