Re: if / else statements not symmetric

Actually I think the code you have in mind is:

#1: *if (X) {A} else if (!X) {B}
#2: *the same

Anything that evaluates X more than once is not correct compilation of the code you originally gave.
Thanks for replying. I took a look at the code I had in mind, and it
was not if/elseif. However, it was a very complex piece of code,
involving evaluating a function that returns a bool [in other words if
(function_retur ns_bool(x,y,z)) {} else {}].

What I did was make the function return the opposite of what it was
returning, (ie. true instead of false) and the program worked
flawlessly, whereas before it was an infinite loop for the reasons I
gave in the OP.

However, I grant that perhaps this fix was due to some peculiarities
of the function, not the if/else statement, so I will retract my
original statement.

And the lesson is: before asserting that a language behaves oddly, try
to find a *simple* example which will demonstrate the issue. If you
manage to find a simple example, that's great and it will add weight
to your complaint. If you can't find a simple example, the problem
probably lies in your complicated code.

So far in Python I've almost hated the 'else' of the 'for' loops: - I have problems to remember its meaning; - It gives me little problems when I later want to translate Python code to other languages (and you always have to translate long-lived code). - I have used it only once, so far. So so far I'd liked to see it removed from Python 3.0. But then this article:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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,...
