Im sorry for asking a question that is surely in the archives somewhere, but
I have been unable to locate it.
Its about string memory management. I need to dynamically construct a
C-style string and was planning to go about it this way;

std::stringstream ss;

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>

I'd like to read stings from cin and put them
in stringstream.
I use a string object as an intermediate "container"
to store data from cin and then put them in stringstream.
stringstream ss ;
string str ;
cin >> str ;
ss << str ;

How do you get rid the contents in a std::stringstream? I'm using one in a
for loop to format some status messages which I print to the screen. The
stringstream member function clear() only clears flags (bits) in the stream,
right? I solved it by declaring the stringstream inside the loop body even
though I have need of another stringstream just after the loop. So for each
iteration the constructor of the stringstream will be executed. Is...

Hi,
I believe that it should not be legal to create a vector (and array) of
stringstream since the copy constructor and assignment operators are
declared private. However, I don't understand why it shouldn't be
legal to create a vector (or array) or stringstream pointers. The
following code compiles and runs on g++, but seg faults while using the
Intel c++ compiler. Is this standard code? Which newsgroup (intel or
g++) needs to be...

Hi,
I feel no doubt some documentation contains my answer, so bare with

I'm trying to get use to using stringstream and I've run across a case
that puzzles me. Perhaps you have some suggestion for the following:
Why in the code below for case 2, intVal is always 1?
// StringToInt.cc

//
#include <sstream>

Hi all!
I have a question about thread synchronization and c++ streams
(iostreams, stringstreams, etc). When optimizing a program for a
multicore processor I found that stringstream was causing a LOT of
synchronization overhead. After a bit of digging I concluded that this
synchronization has to do with the access to a global locale inside
the stream.
The problem can be seen by running the small distilled benchmark code

Hi,
I have a simple nit-picky question. It would be nice for a stringstream to have a member function which returns a C style string (just like a string does) so I could do this,
stringstream ss;
ss << "Etc...";
ss.c_str()
instead of this,

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...
