What's a way of accepting user input directly into a pointer, specifically a string, in c

Bro how to add image in imgui

Here, I googled this for you https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples

Bro tried not working

Input string ab2c4hj3 Output string abbbccccchjjjj

Once u come across a number n, push back the last character u came across n times again

It doesn't work, the program stops at the getline() until the child has terminated

Dear admins. There is a telegram group for Qt cross-platform application development framework. As this framework is primarily based on C++, I would like the experienced people who are actively working on Qt to join the group to share knowledge and answer questions of the group members. I would like to ask the admins whether do I have permission to share the group link here?

If people feel the need to join a QT group, they can very well search for it. We can't let this group become an advertising platform for every C++ project out there.

how can i send array of object as argument with friend function or normal function

C array? You can pass it as pointer to the first element and the size as two arguments. Or if you use C++ you can use std::array of std::vector and pass them by reference or const reference.

It works perfectly fine for me. Do you flush the buffer in the child process after writing to it? If you don't then it would explain the behavior you are experiencing. If you want to see output from the child process as and when it happens, the child process should be flushing the output buffer after every output.

You have to determine what exactly you need: do you need something dynamic in size? If yes you probably want to use std::vector If no, are you manipulating numeric types? If no, std::array is what you need If yes, does your array represent a mathematical vector? If yes, std::valarray may be what you are looking for, check the refs to see if it fits your usecase If no, std::array it is

Only if the storage that pointer points to is allocated using malloc()

Then it's just UB.

Storage made by new[] should be (destruct and deallocate)-ed with delete[]

delete [] ( audio_data )

delete[] audio_data;

Semantically nothing. Choose what you like.

Things done in new/new[] must be finished using delete/delete[], and free() is only supposed to finish what is done in malloc()

class_a *ptr[5]; class_b b[5]; for (int i=0;i<5;i++){ b[i].title="c++"; b[i].edtion="jake"; b[i].num=1048;} //ptr=&b; for (int i=0;i<5;i++){ ptr[i]=&b[i]; search (std::vector<class_b>book , "jake"); search is friend fun. don't Run have error

std::array<class_a*, 5> ptr; std::array<class_b, 5> b; // same code after And your function call is strange, I'm not sure what you've tried to do

i will try many thank my brother 🥀🥀🥀🥀

how i delete it

Calling munmap? https://man7.org/linux/man-pages/man2/mmap.2.html

why its a question

Because I don't know for sure

What kind of function you want to call and what you want to do with it? Can you provide more info?

can i send photo in private ??

error namspace std has no member array

ok array of object friend function to search a title book in array of object found or not in main fun. only invoke friend fun. loop and cout been in friend function

Is it a homework/assignment? Because if yes, they may expect you to do something very specific (and not necessarily something you would do in real code)

assignment

class_a *ptr[5]; class_b b[5]; for (int i=0;i<5;i++){ b[i].title="c++"; b[i].edtion="jake"; b[i].num=1048;} //ptr=&b; for (int i=0;i<5;i++){ ptr[i]=&b[i]; search (std::vector<class_b>book , "jake"); search is friend fun. don't Run have error

Hello my name is Bemigho and I am new to c++. I have been having a hard time understanding pointers and reference. Does anybody know any YouTube channel or a course that can explain it better to me

there is a book directed to C. It is precious on explanations of arrays and pointers named Expert C Programming from Peter van der Linden. It is not difficult to find it in the web. It is from 1994, but still very relevant.
