Describe a type scenario involving 2 computer Devices transferring a video file using an unsecured ftp connection where TCP three-way handshake is susceptible to vulnerability

fill in the correct line of code

 const int PASS = 50;

    int numPass = 0, numFail = 0, totalMarks = 0;

    double mark, perPass = 0, perFail = 0;

    } while (mark > 100);

    // if the inputted mark is not the sentinel value, process it

    while (mark >= 0)

    {

      // increment the counter for the total number of data values

      // *** Insert code

      // Determine if the mark is a pass or fail (If statement)

      // *** Insert code

      // Read next mark

      // *** Insert code

    }

    // Calculate the percentage of marks that were passes and fails

    // *** Insert code
