Guided Practice 1.2

Here is an example based on an exercise from HtDP/2e:

Design a data representation for the following four kinds of zoo animals:

• spiders, whose relevant attributes are the number of remaining legs (we assume that spiders can lose legs in accidents) and the space they need in case of transport;
• elephants, whose only attributes are the space they need in case of transport;
• boa constrictor, whose attributes include length and girth; and
• armadillo, for whom you must determine appropriate attributes; they need to include attributes that determine space needed for transportation.

Write a data definition for ZooAnimal. Be sure to include:

1. Representation and Interpretation
2. Implementation (structure definitions)
3. Constructor Template
4. Observer Template
5. Examples

Here is a solution. But remember, no peeking! You won't get anything out of this exercise if you don't write down your solution first.
