Write a program that prompts for the user’s age and calculates and displays the user’s maximum heart rateand the range of the user’s heart rate.1.Get the user’s age as an integer (int).2.Calculate the maximum rate: maxRate = 220 –age. Calculate the low range: low = maxRate * 0.5. Calculate the high range: high = maxRate * 0.85.3.Output the results as shown below (assumes the user is 15 years old)Yellow are variables:Max rate: 205Low range rate: 102.5High range rate: 174.25
