Help! implement a copy constructor ADT queue in C++

how do you implement a copy constructor for this pointer-based ADT
queue
#include "Queuep.h"
#include <cassert>
#include <new>
using namespace std;

Queue::Queue () : backPtr (0), frontPtr(0)
{
}
Queue::Queue(co nst Queue& Q) throw(OutOfStor ageException)
{
//implement here
}//end copy constructor

Queue::~Queue()
{
while ( !isEmpty() )
{
dequeue();

}//end while
}//end destructor
assert( (backPtr == 0) && (frontPtr == 0) )

You may get better answer in a C++ group.

Probably not. We who frequent the C++ groups recognize homework when we see
it.

After following Microsofts admonition to reformat my system before doing a final compilation of my app I got many warnings/errors upon compiling an rtf file created in word. I used the Help Workshop program: hcw.exe that's included with Visual Basic. This exact same file compiled perfectly with no notes, warnings or errors prior to reformatting my system. Prior to the reformatting, I copied the help.rtf file onto a CD and checked the box to...

A question for gui application programmers. . . I 've got some GUI programs, written in Python/wxPython, and I've got a help button and a help menu item.

Is there a way to get help the way you get it from the Python interpreter (eg, 'help(dir)' gives help on the 'dir' command) in the module cmd.Cmd? I know how to add commands and help text to cmd.Cmd but I would also like to get the man-page-like help for classes and functions. Does anyone know how to do that? Thanks. Sarir

Missing Help Files When I enter "recordset" as the keyword and search the Visual Basic Help index, I get many topics of interest in the resulting list. But there isn't any information available from clicking on many of the available topics (mostly methods but some properties are also unavailable). This same problem occurs with many, if not most, keywords. Is there any way I can activate these "missing" help topics? HELP!

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

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.
