C# Creating a Square

I’m trying to create an application that inputs a Width and Height to design a square. I’ve gotten the error handling for inputting the numbers for the Width and Height. I find myself writing…

//Integer for Width == W
int W;
//Integer for Height == H
int H;
      if (W == 1 && H == 1)
      {
         Console.WriteLine("*");
      }
      else if (W == 1 && H == 2)
      {
         Console.WriteLine("*\n" +
                           "*");
      }
      else if (W == 1 && H == 3)
      {
         Console.WriteLine("*\n" +
                           "*\n" +
                           "*");
      }
     //~~~~~~~~~~~~~~~~~~~~~~~~~~~
      else if (W == 1 && H == 20)
      {
         Console.WriteLine("*\n" +
                           "*\n" +
                          //~~~~~~~
     //For readability 20th"*");

Also, assuming I’d do (else if) another 396 more times to satisfy the variances (20 * 20 = 400) 400 possibilities to build this square.

I’m asking if there is any looping methods that could help me reduce the code I need to complete making my square out of Console.WriteLine("*").

if(W == 1 && H == 1) ~~~ else(W == 20 && H == 20)

Or am I stuck writing the 400 possible instances of the width and height of my square?

The desired result for the display

Thanks for your time and consideration of my question.

>Solution :

You can achieve it via nested loops and a bit of formatting while outputting * to console.

var width = 50;
var height = 50;

for (var x = 0; x < height; x++)
{
    for (var y = 0; y < width; y++)
    {
        if (x == 0 || y == 0 || x == (height - 1) || y == (width - 1))
        {
            Console.Write('*');
        }

        if (x > 0 && x < (height - 1) && y > 0 && y < (width - 1))
        {
            Console.Write(' ');
        }
    }

    Console.WriteLine();
}
