Lab 13: Picture Dynamic Memory
This lab is a paper-and-pencil lab. TAs will manually check your drawings on paper.
Draw the pictures representing each of the declarations below. Each is worth ½ a point, for a maximum of 3.
These problems build on each other, so in some cases a picture refers to something previously created.
