Working with Multithreaded programming!

truongdieulinh

I've justed read some lessons about Multithread Programming, but I don't understand it clearly. There is an example of Multithreaded programming with C#: Calculate N! (N may be greater then 1000) I need someone else to help me. Thanks in advance!

Hix ! The solution of Uz is not clearly to me ! hix ! Can U add more comment for each code line . I will show the code using multitheaded in C# , but this solution doesn't process with N = 1000 and be limited but it is easy to see . Can U repair it ? using System; using System.Threading; class Mythread { public void Factorial() { int n; Console.Write("enter n:="); n = Int32.Parse(Console.ReadLine()); double gt=1; for(int i=1;i<=n;i++) { gt=gt*i; } Console.Write("n factorial:= "+gt); } } class App { public static void Main() { Mythread th = new Mythread(); Thread me = new Thread(new ThreadStart(th.Factorial)); me.Start(); Console.ReadLine(); } }

Hi Does this help? using System; using System.Threading; using System.Runtime.Remoting.Messaging; // create a delegate to the method to be called asynchronously public delegate bool FactorizeDelegate( int factorizableNum, ref int primefactor1, ref int primefactor2); // a class that factorizers the number public class PrimeFactorizer { // method to be called public bool Factorize( int factorizableNum, ref int primefactor1, ref int primefactor2) { primefactor1 = 1; primefactor2 = factorizableNum; // Factorize using a low-tech approach. for (int i=2;i

with N = 1000 :D

Oh yeah hix :(( I dont understand about using multi threads too :( but if using multithreaded programming using C# for calculating N ! (N factorials ) I think It cannot using System; using System.threading; public void cal () { long result = 1; for(int i=1; i<=N; i++) { result *= i; } Console.WriteLine ( "result = " ); Console.ReadLine(); } public static void Main() { System.Threading.ThreadStart ts = new System.Threading.ThreadStart(cal); System.Threading.Thread t = new System.Threading.Thread(ts); t.Start(); } N ! with N = 1000 ! Hmm , may be too large ! Is there anybody here to help us ???
