spliting a list by nth items

by: Steven Bethard |last post by:

I feel like this has probably been answered before, but I couldn't find something quite like it in the archives. Feel free to point me somewhere if you know where this has already been answered. I have a list in a particular order that I want to split into two lists: the list of every nth item, and the list of remaining items. It's important to maintain the original order in both lists. So the first list is simple:

Hi, In my years as a VB programmer, I have settled into this pattern of creating collections classes, with an AddNew() method. AddNew() validates the parameters, instantiates the object, adds it to the collection, and returns it. The AddNew() method was used to get around the lack of a constructor in VB classes. Now I was just about to rewrite this same pattern in C#, when I realized hey ... I've got constructors, and instead of...

C++ Exceptions Cause Performance Hit?

by: kk_oop |last post by:

Hi. I wanted to use exceptions to handle error conditions in my code. I think doing that is useful, as it helps to separate "go" paths from error paths. However, a coding guideline has been presented that says "Use conventional error-handling techniques rather than exception handling for straightforward local error processing in which a program is easily able to deal with its own errors." By "conventional error-handling," I believe...

Exceptions from ESQL/C to DB2

by: N.V.Dev |last post by:

Hi, I have written an ESQL/C program and should any error occur; the same should be displayed as error message. Wrote a test script and expected an exception but DB2 did not throw any such exception rather displayed return = 0 Below is the snippet for ESQL/C #include <stdio.h>

Implementing exceptions of C++ in C

by: Bernard |last post by:

Hi All, I am not sure if I should be asking this question on clc or clc++. Let me try on both. I hope that this is not too trivial for the brilliant minds over here. I know that OOP questions have been asked on clc before so it is probably OK. I am a newbie to C++. BS 3rd edition states: % The throw transfers control to a handler for exceptions .... %

Understanding and Using Exceptions

by: Anonieko |last post by:

Understanding and Using Exceptions (this is a really long post...only read it if you (a) don't know what try/catch is OR (b) actually write catch(Exception ex) or catch{ }) The first thing I look for when evaluating someone's code is a try/catch block. While it isn't a perfect indicator, exception handling is one of the few things that quickly speak about the quality of code. Within seconds you might discover that the code author...

Avoiding Exceptions

by: Jonathan Wood |last post by:

I must be the only one who doesn't think exceptions are the greatest thing since bread. Consider the following code: id = Convert.ToInt32(Request.QueryString); First, is there an easy way to tell which methods or properties could potentially throw an exception? I've scanned the docs and it doesn't seem to say. Without that knowledge, it's a bit of hit and miss.

Should I use exceptions instead of error codes?

by: mike3 |last post by:

Hi. (crossposted because the program is in C++ and some C++-related elements are discussed, hence comp.lang.c++, plus general program design questions are asked, hence comp.programming.) I'm making this bignum package in C++. I'm wondering though on how to handle the errors. Right now most operations routines return error codes if they fail -- but some routines they use inside them, or overloaded operators, will throw exceptions on...

Missing exceptions in PEP 3107

by: Christoph Zwerschke |last post by:

I'm just reading PEP 3107 (function annotations) and wonder why exceptions are not mentioned there. I think it would be helpful if one could specify which exceptions can be raised by a function, similarly to how it is possible in C++ using the "throw" clause. The syntax would be something like this: def foo(a: expr, b: expr = 5) raises expr -expr: The expr in that "raises" clause should be a list of Exceptions.

The easy way to turn off automatic updates for Windows 10/11

by: Hystou |last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

AI Job Threat for Devs

by: agi2029 |last post by:

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
