/* Question := Body Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in 
               kilograms and dividing by the square of your height in meters. Write a program that prompts the user
               to enter a weight in pounds and height in inches and displays the BMI.
                
               Note:- 1 pound=.45359237 Kg and 1 inch=.0254 meters */
