I am a little confused with code I am looking at. My c++ book does not go
into passing a structure to a function so I pulled out a c book which does.
and I do not understand the prototype verses the actual function call. I
will post the code below of the structure, the prototype and and function
call and if someone can explain this I would be very appreciative:
struct data
{
float amount;
string fname;

According to what I have learnt so far, instantiating global objects should
be the last resort. Is there any reasons why so?
Sometimes some objects or their pointers have to be shared among several
other objects, I'd like to know how this is handled commonly. Could someone
elaborate on this?
Another situation is some objects could be shared among several threads.
How to handle it commonly?

Sorry for this very dumb question, but I've clearly got a long way to go!
Can someone please help me pass an array into a function. Here's a starting
point.
void TheMainFunc()

// Body of code...
TCHAR myArray;
DoStuff(myArray);

Hello,
I wonder if I could pick your brains. I'm beginning to learn about C++. I
have opened a file in my program and I want to read lines from it. I would
like this to be done in a separate function called readline() because I
would also like to do some processing on the line each time (ignoring
comments and so on).
I have:

Hello,
i've a outer function, which takes a params-array as a parameter. I
want to pass this array to inner function with a params-array (e. g.

When i've passed an integer to the outer function, the string.format
sets the string-value "System.Object" at the position of {0}.
How can i get it work, so that all my values, passed to the outer

Hello,
Here's the scenario:
Object A opens a Sql Db connection to execute number of SqlCommands. Then it
needs to pass this connection to a constructor of object B which in turn
executes more commands on the same connection.
I have an understanding that if SqlConnection is passed as "value"
(unboxed), object B will create its own copy of SqlConnection, so when
object A closes its connection, it remains open for object B's copy. Is this

Hi all,
I am working on my single instance application that now also has a URL
type associated with it, according to the Asynchronous Pluggable
Protocols information from MSDN. Now, if my application is not already
started, everything works fine. The APP setup starts my program with the
URL as the command line argument, and it displays the proper information
to the user. This works great and was a pleasure to program.
However, my...

I have an application that takes a few command line parameters. As
recommended by others in this group, I'm using a named mutex to ensure
that only one instance of the application is running. My question is
how to elegantly pass a command line parameter from Instance_B to
Instance_A where Instance_A was running prior to Instance_B.
For example, the user can launch the program by passing a file name as
a command line argument. The program...

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,...

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....

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...
