To get all file names in directory
Hi All,
Requirement is:
Need to get all file names in given directory.
I found some ways using third party lib - boost but I am don't want to use it.
I want the solution within standard C++.
Please help me to resolve this requirement.
All suggestions are welcome.
Regards,
Akash

Do you have C++17 (when you say standard C++)?
Because there is this -> https://en.cppreference.com/w/cpp/filesystem
Otherwise, your request is impossible. Standard C++ knows nothing about filesystems.
You have to use whatever comes with your platform, be it
https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-findfirstfilea
or the likes of opendir / readdir / closedir

Hi Salem,
Thank you for the reply.
No for C++17.
I am using Visual Studio 2010 and Windows 7.

Visual Studio 2017/2019 have a free edition, Community.
Either will run on Win 7 w/ SP1, and are C++17 compliant.
https://visualstudio.microsoft.com/vs/
If you are going to upgrade from VS 2010 I'd personally recommend 2019 over 2017.
FYI, 2017 or 2019 do take up a largish amount of HD space.
And C++ infrastructure is not installed as part of a default install. You have to manually select it.

I'd like to add that Boost isn’t exactly “third party” — it is largely written and maintained by people close to (or members of) C++’s steering committee.
I would go as far as to say that any serious C++ programmer should have Boost installed, and it is not unreasonable to require your library/program’s users to have it either.

There IS no solution within standard C++ if you're not using C++17.
I'll say that again.

Your options are:
1) Come up to C++17 and use std::filesystem
2) Use the Win32 API (which is not part of the C++ standard)
3) Use another library (which, again, is not part of the C++ standard - for example, Boost)
