About ProgChecker

ProgChecker - cross-platform separate module of OLSystem, that performs the check of the participants' programs in different programming langyages. The application is a server, that accepts requests for checking task. The programs are checked by multiple programs with different test data for it. This is necessary in order to exclude the possibility of the participant being able to adjust a deliberately correct answer. In order to send the program for verification, you need to cram the request, which will consist of the text of the program and the test data for it. As communication with the OLSystem, the JSON format is used.

Example request
{
    "testData" : [
        {
            "outputData" : "5",
            "inputData" : "5"
        },
        {
             "outputData" : "567",
             "inputData" : "567"
        },
    ],
    "textProgram" : "#include <iostream>
                   
                    int main() 
                    {
                         int tmpVar = 0;
                         std::cin >> tmpVar;
                         std::cout << tmpVar << std::endl;
                         return EXIT_SUCCESS;
                    }"
}

After checking the program, the application sends the result code:

  • 100 - Successful program execution
  • 101 - Error while compiling the program (for compiled languages)
  • 102 - Error during program execution
  • 103 - Security error related to the application and the entire system
  • 104 - Unknown error
Example response
{ 
    "resultChecking" : "100" 
}

At the moment, ProgChecker supports checking programs for the following languages:

  • C/C++
  • Python

But other languages will be added soon.

How to build ProgChecker

cd ProgChecker
mkdir build
cd build 
cmake ..

After that you can use this application. For work with the application, your computer must be installed boost library. It should be noted that ProgChecker isn't required to be used together with the OLSystem. You can install it on the server and use a completely different system with the ProgChecker.

How to start ProgChecker

usage: ProgChecker [PROGRAMMING_LANGUAGE] [COMPILER_OR_INTERPRETER] [ADDRESS] [PORT]

This program checks programs in different programming languages.

arguments:
  PROGRAMMING_LANGUAGE
        name language language for programs(Cpp, C, Java or Python)
  COMPILER_OR_INTERPRETER
        name compiler or interpreter for selected language supported by your OS(gcc, g++, javac, python, clang etc)
  ADDRESS
        address for running ProgChcket in ipV4 fromat.
  PORT     
        port for running Progchecke.
