class Program
{
    // Function to write the given text centered on the screen and then underline it
    public static void WriteUnderlined(string text)
    {
        // Define the screen width as 80 characters
        int screenWidth = 80;

        // Ensure the text is not longer than the screen width, 
        // if it is, truncate it to avoid issues with padding calculation
        if (text.Length > screenWidth)

            text = text.Substring(0, screenWidth);
        }

        // Calculate the padding required on the left side to center the text
        int padding = Math.Max(0, (screenWidth - text.Length) / 2);

        // Write the text with the calculated padding before it, effectively centering it
        Console.WriteLine(new string(' ', padding) + text);

        // After the text, print a line of hyphens, matching the length of the text
        // The number of hyphens is equal to the length of the text

        // Call the WriteUnderlined function with the text "Hello!"
        // This will print the text centered on a screen of 80 characters width, and underline it
