Programming Challenge 4.5 - Body Mass Index

/* Body Mass Index - This program calculates and displays a person's body mass
   index (BMI). 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 displays a message indicating whether the person has optimal weight,
   is underweight, or is overweight. A sedentary person's weight is considered
   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 */
