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 " );
}

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 <string>
#include <vector>
#include <cstring>
// presume s from somewhere, such as:

Can some-one please point me to a nice site that gives an
exhaustive list of all the memberfunctions,
membervariables, operators, etc. of the std::string class,
along with an informative description of how each works.
I've been trying Google for the last 20 minutes but can't
get anything decent.
Thanks.

Hello,
I guess this might be a very dummy question, but I couldn't find an
answer in the group's archive.
I am reading DICOM files, and to store the string read I use
std::string. Unfortunately there is case where the string can be '\0\0'
Is this a defined bahavior when you do this kind of operation :
const char *s = "\0\0";

std::string::npos is described in _TC++PL:SE_ (Section 20.3.4) as the
"all characters" marker. I tried to use it this way, but my program
crashes:
#include <iostream>
#include <string>
int main()
{
std::string s = "hi/hello/now";

I have some C++ unmanaged code that takes std::string& arguments (as
reference), and fills them (possibly growing the string).
I want to call this code through PInvoke (DllImport), possibly using
wrapper layers in unmanaged C++ and C#.
I've thought about two approaches:
1) To pass a StringBuilder, this is converted to a char* in C++, the
wrapper code converts the char* to a std::string (copy), and in the

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,...
