Some people have suggested the desire for code completion and refined
edit-time error detection are an indication of incompetence on the part of
the programmer who wants such features. Unfortunately these ad hominem
rhetorts are frequently introduced into purely technical discussions on the
feasibility of supporting such functionality in C++. That usually serves
to divert the discussion from the technical subject to a discussion of the...

Before launching the instruction xmlDoc.SelectSingoleNode(xmlPath), how
would like to check if my xmlPath exists in the Xml document... it is a soft

What's the proper technique for checking for the existence of an attribute
within a node?
Lets say I did a SelectSingleNode which returned this element:
<AnAddress city="San Francisco" state="CA" />
What's the best why of determining if the attribute zipcode exists in this
node? If I try accessing the attribute with code like:
ZipCode = myNode.Attributes("zipcode").Value

How should we check if the '\0' characters exists in the string as I am
confused that some books mentioned
that we have to check whether we need to make sure that we pass the
'null-terminated-string' to some functions,
such as 'atoi'. (We assume that the string was extracted using an array, not
string literal)
This program shows blank for '\0' for all 3 cases. Why ? And I was trying to
pass some strings formed using an array, without...

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,...

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...
