The RBG queries with only 12% submission, luckily I got through into the 12% but wanted help to decrease complexity to linear

Yeah they have real name SIMD in this case is a custom feature which allows users to disable any SIMD for my VM

Any idea what's wrong here: void* callstack[10]; backtrace_symbols_fd(callstack, backtrace(callstack, sizeof(*callstack)), STDERR_FILENO); ?

It just prints nothing

@lightness_races_in_orbit I figured out backtrace() returns 0. But what's the reason?

Any idea what's wrong here: void* callstack[10]; backtrace_symbols_fd(callstack, backtrace(callstack, sizeof(*callstack)), STDERR_FILENO); ?

Function: int backtrace (void **buffer, int size) Preliminary: | MT-Safe | AS-Unsafe init heap dlopen plugin lock | AC-Unsafe init mem lock fd | See POSIX Safety Concepts. The backtrace function obtains a backtrace for the current thread, as a list of pointers, and places the information into buffer. The argument SIZE should be the NUMBER OF VOID* ELEMENTS that will fit into buffer. The return value is the actual number of entries of buffer that are obtained, and is at most size. The pointers placed in buffer are actually return addresses obtained by inspecting the stack, one return address per stack frame. Note that certain compiler optimizations may interfere with obtaining a valid backtrace. Function inlining causes the inlined function to not have a stack frame; tail call optimization replaces one stack frame with another; frame pointer elimination will stop backtrace from interpreting the stack contents correctly.

In cpp, constructor should be initialized after colon, like : m1(10) But same thing can be done other body of constructor, but not prefered, why?

if m1 is declared as const T, what will happen? Try it.

Hi all, I’m new in learning c/c++ and I’d like to know if a dll (dynamic Library link) can be written in c or c++?

yes you can, there is a book about it on tutorialspoint, it is written with winapi.

Thanks Naol!

It's not important as it is about association of c/c++ files. just let it be default (option: No, leave everything as it is)

Thank you

code blocks is outdated

code blocks is outdated

yea you are right if you mean it has limited features codeblocks is lightweight in comparison to many other IDEs. Also, there are newer versions of codeblocks (the last one is 2020). I think thats why people go for that.

he is jocking, there is 2020 release

he is jocking, there is 2020 release

the 2020 version of codeblocks is not available on Mac The last codeblocks available for Mac is 13.12

So you're trying to install a macOS build of codeblocks onto windows

Have you ever used a computer before?

Lmao

Also I think that's an ancient version you have downloaded

Have you ever used a computer before?

LOL!!!

The OS are different, apps for Mac don't work on Windows.

Also I think that's an ancient version you have downloaded

So what should I download and how?

Which app is better?

Which app is better?

Depends on configuration of your computer, when it's hot I use Mac because it doesn't heat much, when it's cooler I use PC because it's faster... so choice is yours.

can anyone please help me with question: " A state is divided into R*C cities.The government has launched an initiative to find the cities which are dominated by coders. Each city may or may not have coders residing in it. If the city is dominated by coders, it is marked with 1 else it is marked with 0. Two cities are termed as connected cities if they both are dominated by coders and can be reached by moving vertically, horizontally, or diagonally."

Look, if you're actually being serious right now, I do not recommend to start programming. You should first get better computer usage skills

There is no question here + sounds like homework

Windows Forms is deprecated

Well, I advise you to not use WinForms and deal with C++/CLI bs.

you can use external libraries, such as Qt or WxWidgets, MFC is not an easy word to say
