Squares look something like this when drawn 2. Add a constructor that takes the size as a parameter. Store the size in a class variable 3. Add a Draw method that draws the square. The draw method does not take any parameters 4. Create a main) that instantiates a square of size 5 and draws it 5. Also instantiate a square of sze 8 and draw it Optional Chalenge Create a class called Triangle that draws triangles of a specified height. Here is a triangle of height 4 Checklist 1. Project/solution named correctly 2 Correct comments at top 3 Consistent indentation (Use Edit/Advanced/Format Document) 4 Good vaniable names 5 Overall neat organization 6 Comments in code explain what's being done 7 Correct division of code into h and cpp fles 8 Use of #pragma once in h ties (or #mden 9 #rciude "si darm" in cpp files (or suppress pch)Explanation / Answer
