Hi.
Can anyone refer me to any articles about the compatibility between
c++ polymorphism and real-time programming?
I'm currently on a real-time c++ project, and we're having a
discussion about whether we should allow polymorphism. Our system is
not embedded and does not need to be as real-time as, say, a
pacemaker. But it does involve updating displays based on radar
input. So a need for something close to real-time is desired...

assumption: I am new to C and old to COBOL
I have been reading a lot (self teaching) but something is not sinking
in with respect to reading a simple file - one record at a time.
Using C, I am trying to read a flatfile. In COBOL, my simple file
layout and READ statement would look like below.
Question: what is the standard, simple coding convention for reading

Which is best approach?
Should Try + Catch be used to only deal with "catastrophic" events (like
divide by zero, non-existant file, etc...etc...)
Or should Try + Catch be used IN PLACE of regular defensive programming? (ie
if file exists do this, if not do something else)
Or should Try + Catch be used TO SUPPLAMENT regular defensive programming?

I'm maintaining a software project with 134 C++ files, some of
them huge (as much as 10,000 lines each), and very few prototypes.
The author's attitude towards prototypes was like this:
Prototypes are only good for headers to be included in
other files. For functions which call each other inside
one file, such as A calls B which calls C and D,
just define the functions in order D, C, B, A, and you'll
never need prototypes.

Hello all,
I have, what I'm sure is an idiotic question, but I can't seem to find
an answer for it (probably looking in the wrong direction of course).
I'm coming from numerous years in C programming, trying to expand my
horizons and get into C++.
I did a little bit of Java programming along my C days, and this
problem was solved with getParent(), which doesn't pertain to C++ I've read.
So, if I have this:

Hi,
I have a simple question regarding templates and meta programming.
I am going to try and work my way through the C++ Template
Metaprogramming, a book by David Abrahams and Aleksey Gurtovoy. I’m
not doing this because I want to be a Meta Programming guru (because a
lot of that stuff looks too crazy for use in the real world).
Rather I want to learn heavyweight templates and this is the only

Congratulations! You are one of the few who realise that over 80% of errors are simple and easy to fix. It is important to realise this as it can save a lot of time. Time that could be wasted making unnecessary changes, that in turn can cause further problems.
Programming is a humbling experience. An experience that causes one to reflect on human error. One major cause of these errors is syntax, syntax, syntax. We tend not to notice when we...

Yesterday I had a heated discussion with my colleagues on what is a
data centric application and having business logic in sql. I have
group of people who wants to include all the business logic in the sql
stored proc and I for one consider to have most of the business logic
in the C# code (specifically in a controller class of MVC). These are
my points to them.
1. Our application depends a lot on the data and we have huge amount

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...

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...
