REVIEW: struct activities
#8-11 -- Spot the error exercises
Use an object within another object in an activity - #3, 4

Other suggestions:

#6 -- Create a Vector struct (that uses an underlying Carray as a member function)
#7 -- Go over the database code. See if they have any questions and whether they can run a code with multiple files on their computer.
