Data structure Skill examination system

Through one months of efforts, finally the data structure skills test system in C + + language implementation (which has the C language interspersed), the system's greatest advantage is that students can detect whether the answer is inserted in the U disk, opened word and notepad and other auxiliary tools. This system is divided into two parts, part of the student-side, part of the teacher-side.

Students are mainly students enter the number and name (to detect this), according to the number of the last four bits corresponding to the ASCII code modulo 8 evaluation, To achieve the effect of the problem (can also be appropriately improved to IP reading), in the bank to take two questions, random answer a question can be completed after the answer to choose the test, to avoid the topic will not do after the situation. Draw the countdown, the time is 60 minutes, if the timeout, the maximum allowable period of 20 minutes, after the end of the answer can automatically send the program and encrypted student information to the teacher side.

The teacher's function is to obtain the student's file, open its CPP and information file in turn, enter the result, and finally generate the student achievement form. Reduce the need to go to the students to see the program, record the trouble of performance.

Some of the system considerations are as follows:

1. Need to put the file in the D-drive data structure Skills Exam folder, the folder contains a folder named Ti and xuehao,xingming txt text, ti folder put questions, named format for 1.txt,2.txt, Xuehao put the student's school number, Name put the student's name.
2. The student-generated CPP file needs to be opened manually, and if the period is reopened, the countdown starts again.
3. If a USB flash drive is detected by the student, Word will block the problem if it is turned on, and the exam will be valid.
4. The teacher side needs to put the data structure of the D-Disk into the new candidate information file in the test folder and change it to shared mode.
5. The number of students each read by the teacher once fixed, the system will read the corresponding number from beginning to end, regardless of the upload time.
