data structures teacher gave me like 50 questions, I have a few I'm not
sure about. My last c++ class was like 8 months ago and I can't
remember a lot of things. If anyone could help me on any of the
following questions, it'd be great.

I'd like to know why the following program outputs 1, and not 0.
#include <iostream>
class a {
int v;
public:
a():v(0){}
a& operator++(int) {
v++;

I was wondering why the STL RB Tree implementation is
used when the iterators of map are incremented/decremented
to yield successors and predecessors? This takes O(log n)
time (and a lot of memory thrashing depending on the size
of the tree) whereas just a simple pointer chase would make it O(1).
Is there an easy way to code this in C++ (Threaded red
black tree? ) OR Modify map so that map<>::iterator, ++it/--it
becomes O(1)?
Thanks in...

Hello experts,
Why can this difference between prefix increment/decrement and
postfix increment/decrement reside in built-in operators for built-in
data types? Thanks.

I heard people saying prefix increment is faster than postfix
incerement, but I don't know what's the difference. They both are
i = i+1.
i++
++i
Please advise. thanks!!

I'm trying to figure out if an increment to a variable of an integer
type, followed by a decrement, (or vice versa) is guaranteed to restore
the variable to its initial value, even if the first operation causes
the variable to overflow/underflow.
In other words, if foo_t is an integer type, are the following two
functions guaranteed to *always* return a non-zero value?
int check_overflow(foo_t f)
{

Should pre/post increment/decrement return const or non-const?
What about other functions?

The purpose is for a shellsort.
I am experimenting with the increment for shellsort using a modified
version of Pete's driver and this bit of code (shell_ratio is a
floating point number for the time being during my search):

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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....
