Data Structure skill examination system and data structure Examination System

Data Structure skill examination system and data structure Examination System

After one month of hard work, the data structure skill test system was finally implemented in C ++ (with the interspersed C language ), the biggest advantage of the system is that it can detect whether students have inserted a USB flash drive when answering questions, and enable word, notepad, and other auxiliary tools. This system is divided into two parts: student and teacher.

On the student end, the student enters the student ID and name (for this test), and evaluates the value based on the ASCII code 8 corresponding to the last four digits of the student ID, to achieve the effect of question extraction (you can also modify it to an IP address to read the question), extract two questions from the question bank, answer one question randomly, and then select the question after the answer is completed, this avoids issues that will not be performed after the selected answer. When a question is drawn, the countdown is displayed. The time is 60 minutes. If the question times out, the maximum time allowed is 20 minutes. After the answer is over, the program and encrypted student information can be automatically sent to the instructor end.

The instructor-side function is to obtain the student's files, open the cpp and information files in turn, enter the scores, and generate the student scores form. This reduces the trouble of reading programs and recording scores from students.

 

Some precautions for the system are as follows:
