For each problem, study the supplied code, and list the code smells you see. For this exercise the code smells should be one of these:

• long method,
• large class,
• duplicate code (aka cut and paste code),
• long parameter list,
• primitive obsession, and
• magic numbers.

For each code smell,

• list the line numbers of the code where the smell is focused,
• identify the design principle(s) that are violated, and
• identify some program change that the smell would complicate.

Smells and locations?

Design principles?

Maintenance Consequences?
