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 a sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calculated with the following formula: BMI = 703 * weight / height? where weight is measured in pounds and height is measured in inches. The program needs to ask the user (cout/cin) for the information regarding their height and weight. This program must validate that the weight and height are numeric and greater than zero. After the calculation, the program should display (cout) a message indicating whether the person has optimal weight, is underweight, or is overweight (use a decision construct). 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. Finally, let the user repeat the program by asking, allowing them to repeat another BMI calculation... To help expedite the solution you have been given this starting code for your program. Use the given variables for the program and do not declare new ones
