Pattern Series – Hollow Square Star Pattern.

In this post, we’ll explore how to create star-shaped patterns using simple loops in C#.

These exercises may look basic, but they build the foundation for problem-solving and logic — skills every developer needs.

Let’s move to the code example

Create a Static Class named HollowSquareStarPattern

public static void HollowSquareStarPatternFast(int n)
{
    int  i, j;

    for (i = 0; i < n; i++)
    {
        for (j = 0; j < n; j++)
        {
            if (i == 0 || i == n - 1 || j == 0 || j == n - 1)
                Console.Write("* ");
            else
                Console.Write("  ");
        }
        Console.WriteLine();
    }
}

Then call the method in Program.cs

That’s it
