While exercising, you can use a heart-rate monitor to see that your heart rate stays within a safe range suggested by your doctors and trainers. According to the American Heart Association (AHA) (http://bit.ly/AHATargetHeartRates), the formula for calculating your maximum heart rate in beats per minute is 220 minus your age in years. Your target heart rate is 50- 85% of your maximum heart rate. Write a program that prompts for and inputs the user's age and calculates and displays the user's maximum heart rate and the range of the user's tar-get heart rate. Can you do it in C please
