Question

Develop a multithreaded application in C# that creates 4 separate threads. Associate each thread to one distinct method. Each method should contain time-consuming calculations (if you wish, you may use for loops to, to make the execution time even longer.) You may wish to get the input from the user and pass them to the 4 methods that would run in 4 threads you created. The idea is to let all the methods run concurrently. Please make sure that your methods do some useful calculations based on the input entered by the users. Use your creativity for this matter.

Answer 1

Screenshot for code is attached for reference

Program Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleApp5
{
class Program
{
public static void Main(string[] args)
{
//taking user input
Console.WriteLine("Enter an Integer: ");
//converting input string to integer
int n = Convert.ToInt32(Console.ReadLine());

//creating 4 thread and invoking distict method and passing 2 parameters
Thread t1 = new Thread(() => doSomething(n,"Thread1"));
Thread t2 = new Thread(() => doSomething(n, "Thread2"));
Thread t3 = new Thread(() => doSomething(n, "Thread3"));
Thread t4 = new Thread(() => doSomething(n, "Thread4"));
//thread starts when it see this command
t1.Start();
t2.Start();
t3.Start();
t4.Start();

//simple message to mention we are inside main thread
Console.WriteLine("Inside Main Program Last Statement");

}

//Distict method which all 4 threads call to print value of sum
static void doSomething(int n,string str)
{
int sum = 0;
for (int i = 1; i <= 10; i++)
{
//simply we are adding value of i with sum
sum = i + n;
Console.WriteLine("In " + str+ " Value of i is: "+sum);
//if value of sum reaches 7 thread stops or abort
if (sum == 7)
Thread.CurrentThread.Abort(); //we are aborting current thread if criteria met

}

}
}
}

Output
