Hello guys, help me please, i need function for outputting the sum of 3 arrays

what’s wrong with it?

I can’t find such a function on the Internet, it only gives a function to display the sum of all the elements of the array, and I need the sum of the arrays

@hmmmmmhmm

How can i detect most used word sort algorithm in file?

How can i detect most used word sort algorithm in file?

How can i detect most used word sort algorithm in file?

Did you try Googling it?

Did you try Googling it?

i did, but i didn’t find something about that topic

It'd give you lots of examples. But I think you can try reading file, tokenized using space and add to a list, maybe as a struct containing both word and the count.

I tried linked-list to handle datas

Güzel taktik knk :D

Hi

I waiting 🙄🙄🙄

void reversePrintFile() { FILE * dosya = fopen("odev.txt", "r"); FILE * dosya2 = fopen("deneme.txt", "w"); fseek(dosya, -1, SEEK_END); int len = ftell(dosya); len++; while(len--) { char ch; fscanf(dosya, "%c", &ch); if(ch >= 97 && ch <= 122) ch = ch - 32; fseek(dosya, -2, SEEK_CUR); fprintf(dosya2, "%c", ch); } } This code works on Mac, but not in windows I didnt figure it out Can someone help me ?

probably because of file formating (LF, CRLF etc)

Hello everybody, I have such interesting question How to erase or delete from vector of unique_ptr's to incomplete type? I try: auto found = find(cars.begin(), cars.end(), car1); found->reset(nullptr); cars.erase(found) When I use found->reset(); Debuger lead me to unique_ptr.h:402 static_assert(__is_invocable<deleter_type&, pointer>::value, "unique_ptr's deleter must be invocable with a pointer"); using std::swap; swap(_M_t._M_ptr(), __p); if (__p != pointer()) get_deleter()(std::move(__p)); // 402 } When I try with `` Debugger leads to unique_ptr.h:81 { static_assert(!is_void<_Tp>::value, "can't delete pointer to incomplete type"); static_assert(sizeof(_Tp)>0, "can't delete pointer to incomplete type"); delete __ptr; // 81 } ?

1) use found->reset();, not found->reset(nullptr); 2) you are erasing the object referenced by the iterator anyway. why call reset before that. let the destructor handle it

1) And as I already wrote the result of it When I use found->reset(); Debuger lead me to unique_ptr.h:402 static_assert(__is_invocable<deleter_type&, pointer>::value, "unique_ptr's deleter must be invocable with a pointer"); using std::swap; swap(_M_t._M_ptr(), __p); if (__p != pointer()) get_deleter()(std::move(__p)); // 402 } 2) The thing is erase doesn't call for object destructor if a collection holds pointers to objects https://stackoverflow.com/questions/6353149/does-vectorerase-on-a-vector-of-object-pointers-destroy-the-object-itself

using VLAs in C++ is bad style, use std::vector please replace int arr[n]; with vector<int> arr(n); PS: 1) you need to #include <vector> 2) this is still bad style, but it is a direct translation from C style to C++ style

1) need the source code or a manual for the type found::element_type and found::deleter_type

vector uses more memory than arrays?

maybe, but VLAs are unsupported in ISO C++

Can I send you invite link to gitlab? Cause there are not so little files

see if @QNeko's solution fixes the issue

I tried But doesn't know either this advise doesn't help or this style of destructors shouldn't help https://pastebin.com/A1aUcqgr

okay and how are you declaring the vector? std::vector<std::unique_ptr<Car>> cars;?

or did you explicitly mention a deleter function?
