Sorry about the newbie question. What's the best way to convert
numbers to strings in C++. The following works, but is it better than
using the sprintf() "old C" way of converting?
#include <iostream>
#include <string>
#include <sstream>
#include <list>

Hello!
I am using std::stringstream && std::string to parse a text file ->
std::ifstream in;
std::string s;
std::streamstring ss;
int n;
I grab each line like so -> std::getline(in,s);

Hi.
I ran across a bug in one of my problems and after spending some time
tracking it down i found that the problem arose in a piece of code that
essentially did this:
-----------
ifstream in("in.txt"); if(!in) {cout << "error\n";}
in.close(); if(!in) {cout << "error\n";}
in.close(); if(!in) {cout << "error\n";}

I wrote the following function as a curiosity:
template<typename SourceType,
typename DestinationType>
DestinationType NumericCast(const SourceType& value) {
std::wstringstream strbuf;
strbuf << value << std::endl ;
strbuf.flush();
DestinationType convalue;
strbuf >> convalue;

I want to do some find and erase operations that i find in the string
class, upon the entire text contents of a file.
I made a function that will take a string (designed to hold the entire
file contents)
my problem now is how can i grab all the file contents in one swoop and
put it in a string for editing?
I hate to go through the file and copy line by line:

I implemented a codecvt facet (extracted from TCPL) but while it works well
with 'ifstream' it doesn't work at all with 'stringstream'.
Am I missing anything ? I tested it with MSVC 7.1
The code below shows what I'm trying to do:
#include <stdio.h>
#ifdef _WIN32
#include <io.h>
#else

I have a tag like so:
<foo>
and I am trying to extract 'foo' from this.
I'm using a stringstream in a while loop but it seems to fail with the first line, then it works with every other line.
std::ifstream is("xml.txt");
if(is.fail())
{
return 0;

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. The idea...

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...
