One Minute Evaluations for 30 September-2 October

CS 509 - Advanced Programming II

• Topic: I learned that it is very difficult to reliably shrink a vector, and that exceptions are cooler than I thought.

  Question: Could please more clearly explain by example the defining your own exceptions?

  One minute response: Because you can throw a value of any type (except reference types), any type you create can be an exception.

• Topic: We discussed vectors, constructors, functions, resizing vectors, shrinking vectors. We discussed exceptions, need for exceptions, how we use the standard lib, the throw, catch and try statements.

• Topic: Standard template library, containers (vector class), functions of vector class, exceptions, throw, and catch.

• Question: What are standard exceptions? Why is deriving from standard exceptions better? What is minimal compressed path?

  One minute response: Standard exceptions are defined in <stdexcept>. Deriving your own exceptions from the standard exceptions takes less work than deriving from the base exception class. A minimal compressed path is a compressed path with no redundant nodes.

• Topic: This week we talked about STL vectors and exceptions.

  Question: Does STL have its own exception [?]? Like if vector is full, does it throw any any exceptions?

  One minute response: It depends on the implementation, but the STL throws run-time exceptions for things like .at() range violations.

• Topic: STL introduction, STL vectors, exceptions.

  Question: Should we use try{} catch{} in our code?

  One minute response: You should give it a try.

• Topic: Discussed STL introduction, vectors and today we discussed throwing and catching exceptions.

• Topic: We talked about STL vectors & exceptions. in exceptions we talked about try(), catch(), and throw().

• Topic: We talked about vectors, arrays, vector fundamentals, and exceptions.

  Question: Can we catch exceptions that are thrown by the operating system. And display the same [?] as thrown by the operating system.

  One minute response: The exceptions thrown by the operation system are called signals (for unix-like OSs, anyway) and a program can catch signals, but they use system calls rather than language features.

• Topic: This week we talked about vectors and various vector functions in STL and today learned about the exceptions.

  Question: Can you explain the different types of exceptions, for instance IO exceptions?

  One minute response: Unlike Java, there's no fixed differences between C++ exceptions. Any differences that exist are due to conventions, such as logic vs. run-time exceptions. This can make them difficult to distinguish because the meanings are not enforced.

• Topic: We spoke about the STL and some uses of containers essentially an aspect of containers. And exceptions.

  Question: Where do you find the time to conjure up the kind of assignments you do?

  One minute response: A lot of the assignment come from things I read (the unshredding assignment was inspired by an article in the New York Times).
