1. Input the students after login again, how to judge the students have to make an appointment, I tried to use STRCMP function, let enter student id and deposited in the file of student number, the same means to make an appointment, but I tried it on, the input and the last time the same student id, STRCMP function show different,
2. When teachers see students booking situation, how to do it, as shown in the figure, especially the student number and period of time, how did he do in the same article number, (the picture from top to bottom respectively is a date, make an appointment time, booking number, number, booking appointments classmate student id)
