Answer to Question #248819 in C# for Anino

Question

q1) fill in the required code line where //*** insert code is

 const int PASS = 50;

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

    double mark, perPass = 0, perFail = 0;

  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

            double mark, perPass = 0, perFail = 0;


            // loop to read in a valid mark or the sentinel value
            do
            {
                // Read initial mark (seed the loop)
                Console.Write("Enter a mark between 0 and 100 (-ve value to stop): ");
                mark = Convert.ToDouble(Console.ReadLine());
            } while (mark > 100);
            // if the inputted mark is not the sentinel value, process it


            while (mark >= 0)
