How to use C to implement a simple online examination system?

With the rapid development of network technology and computer science, online education and distance learning have attracted more and more attention. Online examination systems have become an important tool for educational institutions and enterprises to assess the abilities of students and employees. This article will introduce how to use C programming language to implement a simple online examination system.

First, we need to define some basic concepts and data structures. The online examination system mainly includes three main entities: test questions, candidates and examinations. We can use C classes to represent these entities.

The test question category can contain information such as test questions, options, and answers. You can define a Question class that contains member variables such as questions, options, and answers, as well as corresponding member functions for obtaining and setting this information.

The Candidate class can contain basic information of candidates and test scores and other information. You can define a Student class that contains member variables such as name, student number, and grades, as well as corresponding member functions for obtaining and setting this information.

The exam class can contain information such as the start time, end time, test questions, and candidates of the exam. You can define an Exam class, which contains member variables such as start time, end time, test questions and candidate list, as well as corresponding member functions for obtaining and setting this information.

Next, we need to implement some basic functions. The first is the test question management function, which can implement operations such as adding test questions, deleting test questions, and modifying test questions. You can use the file reading and writing function of C to save the test questions in a text file, and then add, delete, modify and check the test questions by reading the file.

The second is the candidate management function, which can implement operations such as adding candidates, deleting candidates, and modifying candidate information. Similarly, you can use the file reading and writing function to save candidate information in a text file.

Finally, there is the exam management function, which can implement operations such as creating exams, starting exams, ending exams, and counting scores. When starting the exam, the system can time the time according to the time limit set by the exam and automatically submit the answer sheet after the exam is over. When counting scores, the system can compare the answers submitted by the candidates with the correct answers to the test questions, calculate the scores and save them in the candidate's score list.

When implementing these functions, we can combine C's object-oriented programming and file reading and writing functions to implement a simple but fully functional online examination system.

To sum up, we can use the C programming language to implement a simple online examination system by defining entity classes such as test questions, candidates, and exams, and implementing functions such as test question management, candidate management, and exam management. Meet the needs of educational institutions and businesses for online exams. This system not only facilitates examination and scoring, but also provides real-time statistics and analysis functions to provide better support for education and training.
