"""
In the example above, we create two instances of an Animal.
Then we print out True, the default value stored in hippo’s is_alive member variable.
Next, we set that to False and print it out to make sure.
Finally, we print out True, the value stored in cat’s is_alive member variable. We only changed the variable in hippo, not in cat.
