 using System;
public class Functions

Recursive function in action

Posted on by coder

using System;

public class FactorialTest
{
public static void Main( string[] args )
{
for ( long counter = 0; counter <= 10; counter++ ) Console.WriteLine( "{0}! = {1}", counter, Factorial( counter ) ); } public static long Factorial( long number ) { if ( number <= 1 ) return 1; else return number * Factorial( number - 1 ); } } [/csharp]

Recursive Factorial method.

Posted on by coder

using System;

public class FactorialTest
{
public static void Main( string[] args )
{
for ( long counter = 0; counter <= 10; counter++ ) Console.WriteLine( "{0}! = {1}", counter, Factorial( counter ) ); } public static long Factorial( long number ) { if ( number <= 1 ) return 1; else return number * Factorial( number - 1 ); } } [/csharp]

Use a recursive method, travel, to journey from start to finish

Posted on by coder

using System;

public class Journey {

private static String indent = “”;

public static void TakeOneStep(int step) {
Console.WriteLine(“{0}Taking step {1}”, indent, step);
}

public static void Move(int start, int finish) {
string oldIndent = indent;
Console.WriteLine(“{0}Starting move from {1} to {2}”, indent, start, finish);
if (start < finish) { TakeOneStep(start); indent += " "; Move(start+1, finish); indent = oldIndent; } Console.WriteLine("{0}Finishing move from {1} to {2}",indent, start, finish); } public static void Main(String [] args) { Move(1, 10); } } [/csharp]

Recursive sum method

Posted on by coder

public class SumPrices {

public static double Sum(double[] p, int start, int end) {
if (start < end) return p[start] + Sum(p,start+1,end); else return 0; } public static void Main() { double[] prices = {1.3, 13.68, 314.919, 82.827, 363.949}; System.Console.WriteLine("The sum is {0:C}", Sum(prices,0,prices.Length)); } } [/csharp]
