Lets say I have a char pointer and an std::string. Is it possible to get a
pointer to the std::string's "content" so that the char pointer can point to
the same text? And vice versa; can I give the std::string a pointer and a
length and then give the std::string control over the pointer and its
content?
I'm basically trying to avoid copying large text between an std::string and
a char pointer, and vice versa.
Is there anyhing in the...

Let's say I have a std::string, and I want to replace all the ','
characters with " or ", i.e. "A,B,C" -> "A or B or C". Is the
following the best way to do it?
int idx;
while( (idx=str.find_first_of(',')) >= 0 ) {
str.replace( idx, 1, "" );
str.insert( idx, " or " );

Hi.
q1: Is std::bitset<N> part of standard or it's compiler extension?
q2: Is std::bitset::to_string() part of standard?
q3: My documentation say this about std::bitset::to_string():
"...each character is 1 if the corresponding bit is set, and 0 if it is
not. In general, character position i corresponds to bit position N - 1 -

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...

Dear C++ community,
I have a question regarding the size of C++ std::strings.
Basically, I compiled the following code under two different compilers:
std::string someString = "Hello, world!";
int size1 = sizeof(std::string);
int size2 = sizeof(someString);
and printed out the values of size1 and size2. size1 and size2 always

Hello Experts,
I am using std::string object as a member variable in one of the my
class. The same class member function operates on the std::string
object and it appends some string to that object. My sample code is as
follows.
..h file content----------
#include <stdio.h>

Hi there,
I must be doing something wrong, but I do not understand the
documentation for bitset( string ), shouldn't this be equivalent (ref
== mask ) ?
#include <bitset>
#include <iostream>
#include <string>

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,...
