I am trying to do this:
cin >> temp;
if (temp == "n"){
Then do something...
}
temp was declared as a string and the input I give at the prompt is n, but
it skips the condition for the if statement when I think it should go into
the if statement. I tried swithching to 'n' for the condition but it gave me

Hola-
I didn't get any responses on a previous post, so I am trying to reword my
problem and post compile-able code that exhibits the behavior I am
describing.
On the second iteration of the loop below, the file opened is the default
(which in this case is ".csv", which makes a 'hidden' file for Linux
folk). The step that prompts for a file name step is skipped completely.
Why? Is this a cin issue or does it have something to do with...

Just wondering, for character of arrays, you can set the delimiter manually like
cin.getline(character array, size, delimeter)
But for the STL string, apparently, you have to use the following form of getline
getline(cin, 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...

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...
