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.
Example From Simulation
The following lines are in the Simulation class, and they call a method called InputCoordinate with the parameter value of 'x' and then 'y'.
if (menuOption == 4)
{
x = InputCoordinate('x');
y = InputCoordinate('y');
...
}
The code below is the InputCoordinate method called above. The method expects to be passed a char data type, and within the method this will be called Coordinatename.
private int InputCoordinate(char Coordinatename)
{
int Coordinate;
Console.Write(" Input " + Coordinatename + " coordinate: ");
Coordinate = Convert.ToInt32(Console.ReadLine());
return Coordinate;
This is also a function because InputCoordinate returns a value back (an int).
