Write a program that calculates and displays a person’s body mass index (BMI). The BMI

is often used to determine whether a person with sedentary lifestyle is overweight or

underweight for his or her height. A person’s BMI is calculated with the following formula:

BMI = weight * 703/height2

where weight is measured in pounds and height is measured in inches. The program

should display a message indicating whether the person has optimal weight, is

underweight, or is overweight. A sedentary 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. Use functions for this program. Implement those functions

in a separate header file.
