Does "std::sort" work only with sequence containers, not associative
containers at all?
Among sequential containers, can it be used with "list", "queue" and other
sequence containers besides "vector"?
Are "istringstream" and "ostringstream" covered in the book, "STL Tutorial
and Reference" (second edition) by D. Musser, et al.? Seems like I could
not find any related topic in the book.

I came across code which contains:
std::sort<unsigned char*>((newAnswer.begin()+1),newAnswer.end());
with newAnswer defined as
std::vector<unsigned char>& newAnswer
However upon attempting to compile the above code I got the following

I accidently overloaded a static member function that I use as predicate
in the std::sort() for a vector and ended up with a compiler error. Is
this kind of overload not allowed for predicates and if so, why not?
Shouldn the compiler be able to tell which of he overloaded functions to
use?
The second A::comp() is the one I accidently added and gives the error
message (in Borland C++Builder 6)

I want to sort a vector with the std::sort function. There are two
functions: one with two arguments, the other with three arguments. I
am using the one with three arguments. I noticed that there is a huge
overhead of using this function, which comes from copying the function
object, i.e., the object that compares the elements of the vector,
which is passed to the function not by reference but by value.
Now, at the end of this mail...

Good afternoon,
I need some advice on the following:
I've got a class that has a member
std::vector<CStringm_vFileName and a member CString m_path;
The vector contains a bunch of filenames with no path included
(no C:\...) eg: my_file2.jpg, my_file1.bmp, etc...
and m_path stores the path, eg: C:\folder1
I want to sort this vector according to different criterion, such as

Would std::sort ever compare an object with itself? I'm not talking
about two distinct, equal-valued objects, but rather this == &that.
The container being sorted is a std::vector.
I've never seen this, but a coworker says he is. NB: I can't post
sample code that reproduces the issue, nor do I claim any bug in the
STL implementation (GCC 3.4.2). I'm just hoping a definitive answer
resides in one of the brains who frequent this group.

In the following code example, I define several Comparator classes
which contain different compare functions to use with std::sort. I
have a Sorter class that gets passed a Comparator and is supposed to
sort using the specific Comparator that's passed to it.
But it always uses the Comparator base class and not the derived class
that it is supposed to use, although the functions are virtual.
How can I make the code work? You might argue...

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....
