Assignment 3

Due: Thursday, November 8, 5:30pm (In class)

Weight: 10%

Specification

Code

1. Read comments in the file tool_rental.e. They contain descriptions of methods and pre/post conditions can be extracted from there.
2. Write your assertions in natural language (e.g. as comments in the file).
3. translate required assertions into Eiffel.
4. Spec says:“You are not to implement the body of the routines. But you must implement all supporting quantifier and agent routines. For your support routines you are to write appropriate assertions. For agents the assertions should be compliable. For quantifiers, the assertions should be comments. For all loops in your support routines, you are to write, as comments, loop invariant and variant clauses.”
5. To test your implementation of agents and quantifiers you may add a method in file owner.e (root class of the project) and call it in make feature.

NOTE:

• There may be repetitions in the new_tools and other lists (e.g. two hammers but they should have different ids).

• in new_shop (new_tools : LINKED_LIST[TOOL_DESC] ; min_tool_count : INTEGER) min_tool_count is a min size of the list (can be more tools than min_tool_count in the list). So the new_tools.count should be more than min_tool_count

We will assess if contracts do compile (for compilable contracts) and if they are correct and complete for both compilable and written as comments.
