What are the differences and similarities between Stanley and Zero in Louis Sachar's Holes?

Most of the similarities between Zero and Stanley are based on their personalities. For example, both are adventurous. Zero and Stanley both run away from the camp into the desert, with no water or food. They both also have a sense of justice. They run away to escape the camp's unfair conditions. Their pasts also intersect. Zero is the descendant of Madame Zeroni, while Stanley is the descendant of a man who was supposed to carry Madame Zeroni up a mountain to ensure his future success.

The differences between Zero and Stanley stem mostly from their upbringings. Stanley grew up with two parents and a grandparent, and they all live together. Stanley knows how to read. Zero, on the other hand, does not know where his parents are, and never learned to read.
