4 Computer Programming I TA C162 . 01 Mar 2007 More If Examples if (0 <= age && age <= 11) kids += 1; if (month == 4 || month == 6 ||month == 9 || month == 11) printf(“The month has 30 days.\n”); if (x = 2) y = 5; This is a common programming error (= instead of ==), not caught by compiler because it’s syntactically correct.

    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.
