How to use Multiple Console.Write with for loop?

Question

Hello,

I want to get my value output on the different lines. How do i do that?

using System;

public class _Example
{
    public static void Main()
    {
        for (int counter = 1; counter <= 12; counter++)
        {

           Console.Write(" "+counter);


            if (counter < 5)
    {


                  Console.Write("  " +counter);

        continue;


    }




        }
    }
}

I am getting that output:

11 22 33 44 5 6 7 8 9 10 11 12

When it should be:

1 2 3 4 5 6 7 8 9 10 11 12
1 2 3 4 on a second line

Thank you

@FranK Duc , you could try the following code to seperate the output on 2 different lines.

Code:

                List<int> list = new List<int>();  
                for (int i = 1; i < 13; i++)  
                {  
                    list.Add(i);  
                }  
                list.Take(4).ToList().ForEach(i => Console.Write(" "+i));  
                Console.WriteLine();  
                list.ForEach(i => Console.Write(" "+i));  
                Console.ReadKey();  

Result:

You could re-position the Cursor
To be improved, a quick test :

int nPos = 0;
for (int counter = 1; counter <= 12; counter++)
{
    nPos += counter.ToString().Length + 1;
    Console.Write(" " + counter);
    Console.WriteLine();
    if (counter < 5)
    {
        Console.SetCursorPosition((counter - 1) * 2, Console.CursorTop);
        Console.Write(" " + counter);
        Console.SetCursorPosition(nPos, Console.CursorTop - 1);
        continue;
    }
    else
    {
        Console.SetCursorPosition(nPos, Console.CursorTop - 1);
    }   
}

StringBuilder sb1 = new StringBuilder();
StringBuilder sb2 = new StringBuilder();
for (int counter = 1; counter <= 12; counter++)
{
    sb1.Append($" {counter}");
    if (counter < 5)
    {
        sb2.Append($" {counter}");
    }
}
Console.WriteLine(sb1.ToString());
Console.WriteLine(sb2.ToString());

Answer 4

The loop is fine.

I just want to know how to seperate the output on 2 different lines.

The second Console.Write overlap the first one, thats why data comes out on the same line.

Hello Jack,

Its one complicated way to do it.

There is that solution also: Thanks

using System;

public class Example
{
    public static void Main()
    {
        string firstLine = "", secondLine = "";

        for (int counter = 1; counter <= 12; counter++)
        {
            firstLine += " " + counter.ToString();

            if (counter < 5)
            {
                secondLine += " " + counter.ToString();

                continue;
            }
        }

        Console.WriteLine(firstLine);
        Console.WriteLine(secondLine);
    }
}
