Creating a consol app drawing shapes with asterisks.

Hello, this is my first post here, and won't be my last. I want to really learn this language and not say "give me all the answers so I can get an easy A" I have a friend in C# that tell me to "come up with a string or group of strings defining each shape, and display them using the console write methods (obviously that's easy) what I have so far roughly. The shapes are a diamond, square, oval, and arrow.

using System;
    
     public class Shapes
{

          static void Main(string[] args)

{
       /* I'm assuming here is where you either place the code for strings or declare the strings and values.
       */

          Console.Write("*what the strings output is here or the display of the string(s)*");



}


}


(yes I know the code is messy but this an extremely rough copy)
