Chapter 18, Problem 5ICA

Create an algorithm to classify a given altitude [miles above sea level] entered by the user as in the troposphere, stratosphere, mesosphere, thermosphere, or exosphere. The algorithm should include a check to ensure the user entered a positive value. If a nonpositive value is entered, the program should warn the user and terminate. If the altitude entered is beyond the exosphere, the algorithm should report “Not in atmosphere.” The atmospheric reg1ons are defined by the following criteria:

Troposphere < 12 km

12 km ≤ stratosphere < 50 km

50 krn ≤ mesosphere < 80 krn

80 km ≤ thermosphere < 700 km

700 km ≤ exosphere < 10,000 km
