The problem here is: When I add a 2nd course as an admin, the "Enter course code:" and the "Enter course title:" began to join as one line, and that goes on and on. Please, kindly edit and fix it.
Another problem here is: When I'm about to enroll in a course as a student, the "Enter course code:" and the "You have enrolled in:" joined as one line and I'm not yet inputting something that I enrolled in a certain course which "csit2 programming2" appeared. Please, kindly edit and fix it.
