    public static void WriteTitle(string text)
    {
        // Convert the text to uppercase
        string upperText = text.ToUpper();

        // Calculate the total width (80 characters) minus the length of the title
        int spaces = (80 - upperText.Length) / 2;

        // Create the line of hyphens based on the length of the title
        string line = new string('-', upperText.Length + spaces * 2);

        // Print the top line of hyphens
        Console.WriteLine(line);

        // Print the centered title with spaces on both sides
        Console.WriteLine(new string(' ', spaces) + upperText + new string(' ', spaces));
