One Minute Evaluations for 23-25 September

CS 305 - Computer Algorithms I

• Topic: We talked about ways of organizing and accessing arrays of information.

  Question: No real questions; but I am concerned about the lack of demonstration of syntax for the code we are expected to write for homework.

  One minute response: That's something you're supposed to know walking into 305; at the least, I expect you to be able to find you way around Deitel and Deitel.

• Topic: We talked about records and classes.

  Question: Why has object-oriented programming failed?

  One minute response: It is an ill-defined concept, and so hard to learn and use. People who have defined it in various ways have been unable to get it to consistently produce the benefits it's supposed to deliver.

• Topic: We talked about records and extended our definition to include classes. We compared records to arrays and defined abstract data types.

  Question: How is inheritance done? We never covered it before.

  One minute response: You specify inheritance with subclassing; you implement it using something like unions; and nobody knows how to understand it (or, perhaps more accurately, everybody has a different way of understanding it).

• Topic: We talked about defensive programming and classes.

  Question: Is object-oriented programming the best we can do?

  One minute response: I hope not, because it's not very good.

• Topic: I don't get net code and you expect us to know it, what.

• Topic: Defensive programming, records.

  Question: Are your tests going to continue to be abstract.

  One minute response: Yes.

• Topic: We talked about records and recursive definitions.

  Question: I would like to know if recursive definitions and functions are important?

  One minute response: A person who knows how to use recursive definitions and functions is better prepared than a person who doesn't know how to use them. If being well prepared is important to you, then they're important; otherwise, they're not.

• Topic: Classes and records.

• Topic: We talked about classes and the beginning of Chapter 3, and testing, blowing up or some other stuff.

  Question: When will computers go away?

  One minute response: Probably never.

• Topic: We talked about array algorithms and introduced classes.

• Topic: We talked about the declaration of classes.

• Topic: This week we talked about classes.

  Question: How do interfaces in Java help solve problems with C++?

  One minute response: You can implement Java-like interfaces in C++. The interface mechanism is simpler and cleaner than using multiple inheritance in C++ (although you use multiple inheritance to implement interfaces).

• Topic: Different types of records and the their functional organization; how they accept different data types.

  Question: How do ADTs make it more simple to maintain records in Mass?

  One minute response: I'm not understanding the question.

• Topic: Learned about records, classes, why we use classes.

  Question: What is the commonly used way of sorting?

  One minute response: Probably quicksort, because it's mostly the fastest sort around, except when it isn't.

• Topic: Recursion, structs and classes, core-dump proof coding.
