Does it mean "(sizeof(int))* (p)" or "sizeof( (int)(*p) )" ?
According to my analysis, operator sizeof, (type) and * have the same
precedence, and they combine from right to left. Then this expression should
equal to "sizeof( (int)(*p) )", but the compiler does NOT think so. Why?
Can anyone help me? Thanks.
Best regards.
Roy

Hi I'm learning to code with C++ and wrote some very simple code. I
think it's consistent with every rule but always got compiling errors
that I don't understand.
The code include 5 files as following, delimited by //////:
////////////////pose.h
#ifndef pose_h
#define pose_h
#include "point.h"

Some places till now, I've seen function prototypes within functions
instead of in the global declaration space, which I thought was the
way.
I thought it was <I>only</I>:

Hi,
when a function doesn't specify a return type ,value what value is
returned. In the below programme, the function sample()is returning the
value passed to 'k'.
sample(int);
main()
{
int i = 0,j;
j = sample(0);

I am makeing a Multicast server client setup and was wondering what the
difference is between Socket.Connect, and Socket.Bind.
It may be a stupid question, but I was just curious. Because I tried a
test, and I can't bind two sockets to the same port/ip but I can
connect with one socket, and bind with another to the same ip/port.
Thanks

I currently get asked about my usage of "auto". What is it for?
The keyword is clearly superflous here.
In contrast to the huge majority of C/C++ developers I write
definitions very explicitly like that:
int main(char argc, char *argv, char *env) {
try {
auto Exception mainException(1);
mainException.setErrNo(42);

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.

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...
