How about c++ series from "the cherno" YT channel, I planned to follow this tutorial, what your opinion about this ? 😖😖😖

Well, this is actually not a bad one, but I'm not sure that it is suitable for completely beginners

I saw the update, but what is exactly your problem?

I don't understand, that log doesn't tell me anything about your goal.

why do i sometimes get START MAIN EXECUTOR EXECUTION THREAD IS RUNNING FINISH MAIN EXECUTOR JOINING waiting for EXIT pid 1075525 JOINED and sometimes get START MAIN EXECUTOR EXECUTION THREAD IS RUNNING FINISH MAIN EXECUTOR JOINING waiting for EXIT pid 1075526 wait_for_state (pid 1075523): expected state: EXITED, got state: CONTINUE

or rather, why does the CONTINUE state get caught only sometimes, and not every time?

as both init tests call terminate() explicitly and in the destructor void ExecutionManager::terminate() { if (running.load()) { running = false; for (ThreadCreationInfo * t : threads) { Thread * t_ = &t->thread; if (t_ != this_thread) { if (t_->suspend) continueThread(t_); joinThread(t_); delete t; } } joinThread(this_thread); this_thread = nullptr; threads.clear(); } }

What do you do before the part that says JOINING? I can't find the corresponding code on the gist you sent.

Does anyone know what is the difference between IF / ELSE and SWITCH? When is it best to use each one?

ok i think i got my thread manager stable :)

Does anyone know what is the difference between IF / ELSE and SWITCH? When is it best to use each one?

switch uses a compile-time jump table which is faster than a runtime if else statement which uses conditional branching

if constexpr (C++17) however is computed at compile time instead of runtime

switch uses a compile-time jump table which is faster than a runtime if else statement which uses conditional branching

So the difference would be in which Switch is better optimized

yes

yes

But at compile or run time?

both

Case values in narrow range If the case values are placed in a narrow range, the compiler can avoid performing a comparison for every case leg in the switch statement. In such cases, the compiler generates a jump table which contains addresses of the actions to be taken on different legs. The value on which the switch is being performed is manipulated to convert it into an index into the jump table. In this implementation, the time taken in the switch statement is much less than the time taken in an equivalent if-else-if statement cascade. Also, the time taken in the switch statement is independent of the number of case legs in the switch statement. Case values in wide range If the case legs of the switch statement have a wide deviation in values, the compiler cannot make a jump table to handle the switch statement. In such cases, the jump table would be huge in size and filled very sparingly. Thus the compiler resorts to using a cascade of comparisons to implement the switch. The code generated for the switch statement in such cases will look more like a series of if-else-if statements. Here the time taken to execute the switch statement increases with the number of case legs in the switch. Big switch statement with wide distribution If the switch statement has a very large number of case legs and the values are widely distributed, some compilers use binary search to select the case leg. The different case values are sorted by the compiler at compile time for a binary search.

What do you do before the part that says JOINING? I can't find the corresponding code on the gist you sent.

before that is simply // start ExecutionManager::waitForStop(this_thread); ExecutionManager::continueThread(this_thread); // join ExecutionManager::joinThread(this_thread);

Still confusing to me. Really, I can't grasp the exact problem from your story and piece of code. I would need a minimal working example to compile it myself to see exactly the real problem in front of me in order to find the point you're talking about. But anyway, you've managed to solve it. So I don't really want to ask further detail.

Who we convert letter into ASCII code

Practically, in C, any char is 8-bit integer that contains ASCII code. It is just how you print it. The print format is %hhd for signed 8 bit and %hhu for unsigned 8 bit. No need to cast anything, unless you use insane library like iostream which implicitly prints 8 bit type as character.

The program: Given two angles of a triangle, calculate the third angle. INPUT: A single line containing the two angles a et b separated by a space. OUTPUT: A single line containing the last angle c. CONSTRAINTS: 1≤a<180 1≤b<180 EXAMPLE: Input 1 1 Output 178

how do i solve these kind of problems

thats ok :)

i searched on youtube but they directly solved it without giving proper explaination

Hey why do companies like Amazon etc use c++ for selecting students? Instead no c++ is used for their own development they use java

Amazon uses C++ in the back-end

So what is the work of a c++ dev in Amazon?

So what is the work of a c++ dev in Amazon?

Let's imagine they don't use C++ but they select student who knows C++

Because C++ is one of the hardest language for learning

Ohk

And if someone knows C++ He/She can do anything

Isn't it true that no app is built on single language. It's understandable some parts are written in python. But it doesn't mean they don't use cpp at all. I mean is there any way to actually verify?

And if someone knows C++ He/She can do anything

So people waste 4 year of college to prove that they can do anything 😂

I didn't say that

I said They use C++ But no completely

Oh ok. Sorry. I was just annoyed by answer as it make python seems very much preferably over any other language.

It's not about knowing one kango or not... It's about experience guys.

Every lango has it's own beauty.

I said They use C++ But no completely

If you read the page You will find It's not only they use c++, it depends .most of the software driven technology products are written in python ex Dropbox, one of the best thing created has 20million code in python.

Trust me I just learned C++ But I can do anything by C++ even creating Android apps😂

Hello everyone, I've a problem with passing a parameter to constructor inside a for loop, can anyone help? C++

just post your code and question

let say I've class Student { public: Student(string Name = "XXXX", double English = 100) { this->Name = Name; this->English = English; } private: string Name; double English; };

So when I'm trying to create the list of 5 people by using a for loop, it's showing me an error: for (int i = 0; i <= 5; i++) { cin >> Name; cin >> English; Student s[i](Name, English); }
