Hi,
I have been reading some text on C and C++ (i.e advanced books). One
of the books mentioned that C++ requires a runtime support whereas C
does not - what the author was trying to say was that once you compile
a C program the executable created is all that is needed whereas if you
compile a C++ program the executable created requires a C++ runtime
installed on your system to run the program.
Can someone please provide more...

Could someone tell me how to open a file at run time
that I didn't know the name of at compile time?
I know how to open a file at compile time when I know
what the name is going to be.
FILE *p_afile;
if((p_afile = fopen("shoppinglist.txt", "r")) == NULL)
{
fprint("Could not open file");

Hi, I understand the concept/definition of polymorphism. But what does the
term "runtime polymorphism" mean? I was asked to define it during a
technical interview. I gave a guy vanilla definition of polymorphism, but he
insisted on runtime. Did I miss a new buzzword while I was sick with the flu
last week or something like that?

This is a weird one.
I have a series of "SmartParts" which are CAB (Composite Application Block)
Views which are finally just UserControls (99% of the time)
Anyway, I layout my UserControl in the VS2005 designer, but at runtime, the
controls are in different locations and different sizes. I have been able
to restore their sizes by putting a hack together that will set their sizes
to the correct values in the UserControl's Resize...

Hello,
Can I have runtime polymorphism using references. I knew that runtime
polymorphism could be obtained only by pointers, but now I have tried
this in Visual C++ 8.0:
#include <iostream>
using namespace std;

I've been compiling a list of the differences between C and C++, and
I'd like to see how thorough I've been. Could any of you go over this
list and see if I've missed anything?
Here's the list:
Mid-scope declarations
Default function parameters
new/delete operators
Better implementation of const

I have read that using templates makes types know at compile time and
using inheritance the types are first decided at runtime. The use of
pointers and casts also indicates that the types will first be know at
runtime.
But is there some strict definitions that defines runtime code and
compile time code that can be used in general?

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
