is there a way to have line amount higher than 6, when my array bound is set to 6?-CodePudding

I would like to print out more than six lines of six random numbers, but array bound is blocking me. I have set my array 'numbers' to six in order to always get just six random numbers, but now I dont know what to do to print out for example just ten lines of the numbers, because as I said - I can not due to six bounded array and I do not know how to deal with it. Can anyone help, please?

using System;


class Program
{
static void Main()
{
    Draw();
    Console.ReadKey();
}


static void Draw()
{
    int choice;
    Random randomNum = new Random();
    int[] numbers = new int[6];
    Console.Write("enter line amount: ");
    choice = int.Parse(Console.ReadLine());
    for (int i = 0; i < choice; i  )
    {
        Console.Write("\n");
        for (int j = 0; j < numbers.Length; j  )
        {
            numbers[i] = randomNum.Next(1, 49);
            Console.Write("{0} ", numbers[i]);
        }
       
    }
  
   
}

}

Hy!

In the 2nd for loop, write "j" instead of "i", because the 2nd for loop monitors the length of the array

Try this:

static void Main(string[] args)
    {
        Draw();
        Console.ReadKey();
    }


    static void Draw()
    {
        int choice;
        Random randomNum = new Random();
        int[] numbers = new int[6];
        Console.Write("enter line amount: ");
        choice = int.Parse(Console.ReadLine());
        for (int i = 0; i < choice; i  )
        {
            Console.Write("\n");
            for (int j = 0; j < numbers.Length; j  )
            {
                numbers[j] = randomNum.Next(1, 49);
                Console.Write("{0} ", numbers[j]);
            }
        }
    }

Arrays in C# are of a fixed size, so I'd recommend using a dynamically-sized collection, such as a List<T> instead in your case.

There's a good introduction on how to use these on Microsoft's documentation here if you aren't familiar.
