Question

Write   a   program in Visual C# that   generates   1000   random   numbers   with   a   user   provided   seed and upper   limit   on   the   random   numbers   generated. The numbers should be stored in a text file, each appearing on a newline, using   the   Windows   Save   File   dialog.   Each   number   should   be   separated   by   a   newline.      
  

Answer 1

NOTE:- Notepad skips Line Break So try editors Like Sublime for open saved File

-> I am running in Sublime editor and compiling using Power Shell, you can use CMD, Visual Studio or any other program you want

-> I also included lower Limit

Running Process:

FILES:

numbers.txt

.......

CODE: (Text Code Also included in End)

CODE:

using System;
using System.IO;
using System.Windows.Forms;

// namespace declaration
namespace MyAPP {
    
    // Class declaration
    class NumberGenerator {
        
        // Main Method
        [STAThread]
        static void Main(string[] args) {
            
            // Variables
            int seed, upperLimit, lowerLimit;
            string numbers = "";

            //Taking Input
           Console.Write("Enter Seed Value: ");
           string userInput = Console.ReadLine();
           /* Converts to integer type */
           seed = Convert.ToInt32(userInput);

           Console.Write("Enter Lower Limit: ");
           string userInput2 = Console.ReadLine();
           /* Converts to integer type */
           lowerLimit = Convert.ToInt32(userInput2);

           Console.Write("Enter Upper Limit: ");
           string userInput3 = Console.ReadLine();
           /* Converts to integer type */
           upperLimit = Convert.ToInt32(userInput3);

           // Generating 1000 Numbers
            Random rand = new Random(seed);
            for(int i = 0; i < 1000; i++)
           {
               numbers += rand.Next(lowerLimit, upperLimit);
               numbers += "\n";
           }

           //Saving File
           SaveFileDialog savefile = new SaveFileDialog();
           // set a default file name
           savefile.FileName = "numbers.txt";
           // set filters - this can be done in properties as well
           savefile.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";

           if (savefile.ShowDialog() == DialogResult.OK)
           {
                using (StreamWriter sw = new StreamWriter(savefile.FileName))
                    sw.WriteLine (numbers);
           }

        }
    }
}
