it brings confusion if your code is confusing

Well codes like a[++i] = i; is hard to read anyway, but valid after C++17
Jussi
indeed, but afaik it is always the coder's responsibility to keep their code readable
Jussi
but I agree, that is stupid to allow

Any recommendations on how to start learning STL Lib except geekforgeeks?
You can refer to the documentation on en.cppreference.com and try doing simple problems on platforms such as TopCoder, LeetCode, Kattis, HacherRank to get a feel for data structures involved

If en.cppreference.com is a little arcane to read then perhaps cplusplus.com would be easier

Not sure how in depth the coverage of STL is but I saw a video of his explanation of algorithms and it was quite easy to follow along so I would recommend his Udemy course

Else I would know it^^

US$9.99 hmmm ( Xscore == Xcode... I can't really catch that accent

my 1990ish C++ book teaches conio and iomanip :/

conio seems to be an underpowered ncurses 🤔

I’m getting a libc++.dylib exception thrown when running a debug config for my project on CLion. Has anyone encountered this before?

have you linked against your stl's object file?

I encountered when trying to set up a CMake project. How do I go about the linking?

Clion uses cmake iirc. If the clion gui is shitty have a look at your CMakeLists.txt

Well one of my team members did most of the configs because he is more familiar with CMake. The issue arose mainly because we wanted to develop cross platform since there is at least one team member using either Linux (Ubuntu), Mac or Windows. Anyways that issue seems to be sorted. From what I read online the posts seem hinted in the direction of problems with XCode. I recently deleted the XCode application from my Mac and that caused me some issues elsewhere too. Could that be responsible for this issue as well?

I have only like 14GB of free space left and installing XCode itself requires about 20GB apparently

So what's the libc++.dylib exception exactly?
Anonymous
Ok so when I run the project the message I get is "libc++abi.dylib: terminating with uncaught exception of type std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >"
Anonymous
Something related to string but can't tell what exactly

Where does this exception occur?

It just show up when I run a program called autotester written in C++

But I don't think it's a problem associated with the AutoTester program itself

Hello all) I have stupid question. But I want to understood what is happens. So why this isn't equals nullptr after I delete them? class B {
public:
std::string name;
explicit B() {
cout << "Constructor" << '\n';
}
void some() {
std::thread temp_thread([this]() {
std::this_thread::sleep_for(std::chrono::seconds(2));
if (this != nullptr) {
cout << this->name << '\n';
}
});
temp_thread.detach();
}
~B() {
cout << "Destructor" << '\n';
}
};
int main() {
B* b = new B();
b->name = "Silvestr";
b->some();
delete b;
std::this_thread::sleep_for(3s);
return 0;
}

Because delete means: take what is at that memory address and clean it up so that I can forget about the address, but it will not change the address b itself

thank you) short and clean explanation.
Silvestr
but what happens with that address?
Silvestr
Can I reuse it in future?
Silvestr
For example for another new allocations
Anonymous
If the new allocation points to the same address, than you can reuse it. If you use the address after delete, it results in undefined behaviour.

oh I understood after delete I free everything that relates for this pointer and just have address that can be used again.
