Parameter Passing - 2017

Parameter passing is inserting values into methods or calculations using a declared variable, rather than the raw data (strings, numbers, bools, etc.). This can be done in multiple ways, but the most often used (in the skeleton program) will be:

 int a = 10;
 string b = "yes";

 Console.WriteLine(a);
 Console.WriteLine(b);

The parameters a and b are passed to the WriteLines.

From Simulation:

 if (menuOption == 4)
        {
          x = InputCoordinate('x');
          y = InputCoordinate('y');
        ...
        }
    private int InputCoordinate(char Coordinatename)
    {
      int Coordinate;
      Console.Write("  Input " + Coordinatename + " coordinate: ");
      Coordinate = Convert.ToInt32(Console.ReadLine());
      return Coordinate;

The method InputCoordinate declares x and y as int, the chars 'x' and 'y' are passed into InputCoordinate to use.
