The American College of Sports Medicine recommends that you maintain your training heart rate during an aerobic workout. Your training heart rate is computed as .7 * (220 - a) + .3 * r, where a is your age and r is your resting heart rate (your pulse when your first awaken). Write a program to request a person's age and resting heart rate and display their training heart rate. See Fig. 2.8.
