Hello,
I am trying to read a big file into a string. AFAIK std::string can read
in words or "lines" from a stream. So one option is to continuously
append all the "lines" from the file to the string.
The second option is to use the istream::read(Ch *p,streamsize n)
function and then create a std::string from 'buf'. However this is a
waste of time and space because (if I am not mistaken) the std::string
constructor will make a copy of...

I'm re-evaluating the way that I convert from a std::string to char *.
(Requirement: the source is a std::string, the usable contents are char *)
Here is what I've come up with:

#include <vector>
#include <cstring>

Is there any way I can reduce the size of internal buffer to store
characters by std::string?
After having used a string object to store large strings, the object
seems to
retain the large buffer as I found out calling by capacity().
What if I do not need all that buffer space again want to reduce the
size to
a smaller one? I tried resize() passing a smaller size than the

First of all, forgive me if this is the wrong place to ask this question,
if it's a stupid question (it's my second week with C++), or if this is
answered some place else (I've searched but not found anything).
Here's the problem, I have two sets of files, the name of a file contains a
number which is unique for each set but it's possible (even probable) that
two files in different sets have the same numbers. I want to store these...

Hello, I am working on cleaning up some code that I inherited and was
wondering if there is anything wrong with my function. I am fairly
proficient in standard C++ but I am pretty new to the .NET managed C++.
It seems to work fine, but everyone knows that programs with errors can
still appear to "work fine" :)
I am working with VS .NET 2003; I am unable to upgrade to 2005 at this
time, so I cannot use the newer syntax or features.

Hello,
For many years ago I implemented my own string buffer class, which
works fine except assignments - it copies the char* buffer instead of
the pointer. Therefore in function calls I pass "const char*" and get
the result in a parameter by reference "MyString& result".
I'd like to move to nicer strings. In order to keep platform/compiler
independence I consider std:string as the replacement. While googling
I managed to read some...

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...

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....

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...
