Import .cpp based problem to domjudge?
by gugelgantengbanget＠gmail.com 30 Jun '22

30 Jun '22

Hello, I'm currently new in this field and want to ask a few questions regarding creating a problem on domjudge. First of all, I have one problem and I want to add it to the domserver. I have the pdf (text) for the question and .cpp for the solution. What do i have to configure to add the problem to the server, what is the meaning of run and compare script, and how do I insert the .cpp solutions file to the problem? Thank you!

Greetings, My name is Michalis Kilikis and I am senior student in Technical University of Crete in Greece in the department of computer science. For my thesis project, I want to develop an API for Moodle (for starters), that can automatic grade Student's code questions. My API will take as input the student's code and a series of test cases. I wander if it is possible to use your Platform for sandboxing. Sincerely, Michalis Kilikis

Hi, Thanks for your response, please could you explain more detail how to pass $request to function so that the system processing it? I'm not familiar with Symfony. >> To get the request info, pass Symfony\Component\HttpFoundation\Request $request to the function and check >> $request->query->getBoolean(’static’) Actually, I would like to set the static value to 1 in RootController before redirect it to public_index, so I need to get the request and set that value.
