panda challenge with struct

Hi Jesse,

So I have achieved the output for the Panda challenge BUT I am using struct and have some questions:

1. can you treat a <code>struct</code> as you would a <code>class</code>. Is my method appropriate?
2. in order to move forward with the tiger challenge, I will need the <code>struct</code> to inherit from the "vehicle" <code>class</code>. Is this possible?
