While spending the summer as a surveyor’s assistant, you decide to write a program that transforms compass headings in degrees (0-360) to compass bearings. A compass bearing consists of three items: the direction you face (north or south), an angle between 0 and 90 degrees. And the direction you turn before walking (east or west). For example, to get the bearing for a compass heading of 110.0 degrees, you would first face due south (180 degrees) and then turn 70.0 degrees east (180.0 – 110.0). Be sure to check the input for invalid compass headings.
