Body mass index (BMI) is a number calculated from a person’s weight and height. According to the Centers for Disease Control and Prevention, the BMI is a fairly reliable indicator of body fatness for most people. BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual-energy X-ray absorptiometry. The formula for BMI is

weight / height2

where weight is in kilograms and height is in meters.

(a) Write a program that prompts for metric weight and height and outputs the BMI.

(b) Write a program that prompts for weight in pounds and height in inches, converts the values to metric, and then calculates the BMI.
