2. Suppose that a student has the option of enrolling for a single elective during a term. The student must select a course from a limited list of options: English, History, Economy, Chemistry, or Physics. Construct a fragment of MATLAB code that will prompt the student for his or her choice, read in the choice, and use the answer as the case expression for a switch construct. Be sure to include a default case to handle invalid inputs. Testing three cases: (a) Chemistry (b) Physics (c) Biology
