APSC 160: SAMPLE MIDTERM EXAMINATION S OLUTIONS Don't even think about looking at these solutions unless you've put serious effort into coming up with your own solution. Reading a solution that someone else put together is easy and, in itself, will not prepare you for the midterm exam. You need to be able to come up with these solutions on your own! Note: 1) Many people lost marks on Q4A because they did not read the question. If you do not make use of the printStars function, you will lose marks, even though your solution "works". 2) Many people lost marks on Q4B because they did not follow the hint provided. If your solution does not make use of the function written in Q4A, you will lose marks, even though your solution "works". 3) Many people lost marks on Q5B and Q5C because they did not make use of the symbolic constants provided. 4) Many people lost marks on Q5C because they did not make appropriate use of if-else statements and/or their solution incorporated redundant Boolean expressions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
