i know but you have to use simple syntaxs

Your university professor is an idiot

Even worse

you mean this question is wrong ?

The problem isn't trivial enough to be solved by highschool students. Sure you can come up with a solution that works well enough for small numbers. But the problem with floating point is inaccuracy as the number gets bigger. If you're planning on dividing and using mod to figure out the digits in reverse, that may not give you accurate results on sufficiently large numbers.

i know its hard to solve but i have to solve it

it's quite easy actually, just convert it to int so you don't get more inaccuracy and then reverse it

That doesn't work, you cannot represent all floats as ints

it's precision is 6 digits, i think you are fine with using int :)

What? Where are you getting that idea from?

??

Your "solution" is incorrect and faces the exact issue I was talking about, why are you bringing it up in the first place?

You mean the issue that the question problem is so hard for highschool students that it cannot be solved? You said to use strings which is just overkill like you have been told. I think casting float to int would be considered basic features as opposed to sprintf

If you want to implement it correctly, you're stuck with extracting all digits from a floating point number, sprintf does exactly that. Doing this is not a trivial task. As I said before, implementing a solution that works sometimes is easy, but it will give you wrong results and no real way of doing error handling. I don't believe that this Problem should be asked in highschool because it's not to be solved by someone who doesn't understand the ins and outs of floating point

Hi! I am trying to compile add libsnark in my project and have an error. I've set std=c++11 to libsnark project and original project has 20 std /usr/local/include/libsnark/knowledge_commitment/knowledge_commitment.hpp:40:33: error: expected unqualified-id before ‘)’ token\ 40 | knowledge_commitment<T1,T2>() = default; | ^ compilation terminated due to -Wfatal-errors.

send code screenshot

why?

Hey computer scientist cuz of danya i search about Qt and im not clear on some things does Qt provide a open source library like math.h ,etc or we must download the Creator to use in windows cuz i dont got one :)

Can i ask you for electronic engineer which programming languange should i learn

hello, I have a problem here, In my learning , there is a task to write a simple shell in C. I am using getline to get user input, but theres an issue with EOF (Ctrl+D) in the regular shell, it seems that when I input EOF it is ignored, but in mine when I input EOF, I can no longer delete/edit behind the point where I pressed Ctrl+D at. how do I handle this EOF?

What is regular shell? As you already figured out your shell may do some voodoo with keypresses and translate it to signal, ignore it, turn it into another character....

Just pick terminal which works for you and show it to the teacher...

There are many shells and each shell behaves differently. So the term regular shell could mean different things for different people. For ex I use fish and others may use bash or csh. So you can implement a specific feature the way you want it and describe the behavior of your shell to your teacher.

Shell itself is not part of the kernel, it is just an application program written on the basis of the kernel

yeah, I meant that I am using bash, and that I want to replicate its behavior when Ctrl+D is pressed on my simple shell

I meant shell. I want to be able to press ctr-D and have it not affect my input

So which one is for beginners and veterans?

What would be the shortest introduction to C++ for someone coming from a C background?

A Tour of C++ 3rd edition from Stroustrup, I would say

Guys, what your thoughts and opinions about learning DSA? Should I try to learn this concept using my knowledge of C ( it's basic, so in the journey I improve my c background) or just learn this concepts using any tool, because the application in the end is the same anywhere?

It skips a lot of legacy stuff and C stuff that you already know and goes through the most important features of the language, and the most recent stuff too

991 pages.. Oh no

Why does this yield A AA AAA Instead of, A BB CCC

Because variable ch defined inside second while loop body, move to one level higher, where j is defined

Now I've done what you've said,the output is(for n=3) : A AB ABC

I suppose the tool shouldn't matter, but definitely use C

hey is there a way to initialize vector at one place and then declare later the space it requires, ideal way to do it is : vector<int> v(10,0);

Arrays, Lists (Singly Linked and Doubly Linked), Graph representations like Adjacent Matrix, Edge graphs and so on, Graph Algorithms, String Algorithms like Burrows Wheeler, Rabin Karp, Morris and so on, Dynamic Programming, Greedy Algorithms, Streaming Algorithms et al. That should be the syllabus. I have checked the question paper for Algorithms in my university which account for most of these questions. Your university would do the same if it intended to check a student's understanding of the concepts Please stick to C/C++ questions in future unless you want to get banned
