Through one month's efforts, the data structure skills examination system was finally implemented in C++ language (including C language interpolation). The greatest advantage of the system is that it can detect whether students have inserted U disk when answering questions, and open auxiliary tools such as word and notebook. This system is divided into two parts, one is student-side, the other is teacher-side.
The student end is mainly the student input the student number and name (to test it). According to the ASCII code 8 corresponding to the last four digits of the student number, the result of the problem extraction can be achieved (also can be improved to IP reading questions). Two questions can be selected from the question bank and one question can be answered randomly. After the completion of the answer, the selected questions can be selected to avoid the situation that will not be done after the selection of the questions. The countdown time is 60 minutes. If the timeout is over, the maximum allowable time is 20 minutes. After the answer, the program and encrypted student information can be sent to the teacher automatically.
The function of the teacher end is to get the students'files, open their CPP and information files in turn, and input the results, and finally generate the students' performance forms. Reduced the need to go to the students to watch the program, record the results of the trouble.
Some considerations of the system are as follows:
- The files need to be placed in the folder of the D-disk data structure skills examination. The folder contains a folder named Ti and the TXT text of xuehao and xingming. The Ti folder contains test questions in the naming format of 1.txt,2.txt, etc. xuehao releases the student's school number and the student's name.
- The cpp file generated by the student side needs to be opened manually. If it is reopened during the period, the countdown starts again.
- If the student side detects the U disk, word and so on, it will shield the questions, and then the examination can be continued only after it is legal.
- Teachers need to change the new candidate information file in the D-disk data structure skills examination folder into a shared mode.
- Once the number of students read by the teacher is fixed, the system will read the corresponding number from beginning to end, regardless of the upload time.
