Exercise:

Class ScreenText


Objetive:

Create a class ScreenText, to display a certain text in specified screen coordinates. It must have a constructor which will receive X, Y and the string to write. It must also have 3 setters and a "Display" method.

Create a class CenteredText, based on ScreenText, to display text centered (horizontally) in a certain row of the screen. Its constructor will receive only Y and the text. SetX should not change the horizontal position.

Create a class FramedText, to display text centered and inside a rectangle. It will receive the starting row and the text.

Finally, create a test program for all of them, which will create an object of each type and display them.


Code:

using System;
namespace TextScreen
{
    class CenteredText : ScreenText
    {

    }
}

using System;
namespace TextScreen
{
    class Program
    {
        static void Main(string[] args)
        {
        }
    }
}

using System;
namespace TextScreen
{
    class ScreenText
    {
        protected int x, y;
        protected string text;

        public ScreenText(int x, int y, string text)
        {
            this.x = x;
            this.y = y;
            this.text = text;
        }

        public void SetX(int x)
        {
            this.x = x;
        }
        public void SetY(int y)
        {
            this.y = y;
        }
        public void SetText(string text)
        {
            this.text = text;
        }

        public void Display()
        {
            Console.SetCursorPosition(x, y);
            Console.Write(text);
        }
    }
}
