I was recently part of a little debate on the issue of whether
constants and string literals are considered "data objects" in C. I'm
more confused now than before.
I was always under the understanding that only "named" storage
areas(from the standard) were data objects. Since constants and string
literals don't have lvalues, they can't be data objects. Yet, I was
shown the first page of chapter 2 in K&R2, which states that variables...

I've got different result when comparing two strings
using "==" and string.Compare().
The two strings seems to have same value "1202002" in
the quick watch, and both have the same length 7 which I
have tried to print out by debug.writeline().
But the "==" operator results false, and string.Compare()
results true.
Somebody helps me!

I've been perf testing an application of mine and I've noticed that there
are a lot (and I mean A LOT -- megabytes and megabytes of 'em) System.String
instances being created.
I've done some analysis and I'm led to believe (but can't yet quantitatively
establish as fact) that the two basic culprits are a lot of calls to:
1.) if( someString.ToLower() == "somestring" )

Can you do a search for more that one string in another string?
Something like:
someString.IndexOf("something1","something2","something3",0)
or would you have to do something like:
if ((someString.IndexOf("something1",0) >= 0) ||
((someString.IndexOf("something2",0) >= 0) ||

This is such a long posting that I've broken it out into sections.
Note that while developing this patch I discovered a Subtle Bug
in CPython, which I have discussed in its own section below.

THE OVERVIEW
I don't remember where I picked it up, but I remember reading years
ago that the simple, obvious Python approach for string concatenation:
x = "a" + "b"

I am interested in scanning web pages for content of interest, and then
auto-classifying that content. I have tables of metadata that I can use for
the classification, e.g. : "John P. Jones" "Jane T. Smith" "Fred Barzowsky"
"Department of Oncology" "Office of Student Affairs" "Lewis Hall" etc. etc.
etc.
I am wondering what the efficient way to do this in code might be. The dumb
and brute-force way would be to loop through the content...

1. If I pass pointers (char*) as iterators to an STL algorithm and the
return value is an iterator, can I convert that iterator to a pointer? If
yes, how?
2. What is the internal representation of vector<string>? Will the vector
contain the string objects or will it contain pointers/references to the
string objects? The reason I ask is that it is not clear to me how the
v.reserve() and &v operations would work for a vector<string>.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
