declaring methods with multiple parameters

1   // Fig. 7.2: MaximumFinder.cs
 2   // Method Maximum with three parameters.
 3   using System;
 4
 5   class MaximumFinder
 6   {
 7      // obtain three floating-point values and determine maximum value
 8      static void Main()
 9      {
10         // prompt for and input three floating-point values
11         Console.Write("Enter first floating-point value: ");
12         double number1 = double.Parse(Console.ReadLine());
13         Console.Write("Enter second floating-point value: ");
14         double number2 = double.Parse(Console.ReadLine());
15         Console.Write("Enter third floating-point value: ");
16         double number3 = double.Parse(Console.ReadLine());
17
18         // determine the maximum of three values
19         double result = Maximum(number1, number2, number3);
20
21         // display maximum value
22         Console.WriteLine("Maximum is: " + result);
23      }
24
25      // returns the maximum of its three double parameters
26      static double Maximum(double x, double y, double z)
27      {
28         double maximumValue = x; // assume x is the largest to start
29
30         // determine whether y is greater than maximumValue
31         if (y > maximumValue)
32         {
33            maximumValue = y;
34         }
35
36         // determine whether z is greater than maximumValue
37         if (z > maximumValue)
38         {
39            maximumValue = z;
40         }
