Function Write Centered - C# Programming Exercise

In this C# exercise, you are asked to write a function that displays the given text centered on the screen (assuming a screen width of 80 characters). The code should look something like this:

WriteCentered("Hello!");

The WriteCentered function must accept a string parameter (in this case, the text "Hello!") and display it centered on the screen, taking into account a width of 80 characters. To solve this exercise, you will need to calculate the available space before and after the text to center it. This exercise is useful for practicing how to manipulate strings and work with text alignment in the C# console, and it is especially helpful to understand how to control the output format on the screen.

Example Code Copied

// Importing the System namespace to access basic system functions
using System;

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

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

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

    // Main method to call the WriteCentered function and display the result
    public static void Main()
    {
        // Call the WriteCentered function with the text "Hello!"
        // This will print the text centered on a screen of 80 characters width
        WriteCentered("Hello!");
    }
}
