If you want a laugh, Google a tutorial for how to read a file. You should also know that all the tutorials are wrong, because they fail to handle at least one footgun or another.

There is no “modern” alternative. If you read Reddit threads, C++ programmers actually believe that it’s a reasonable file reading API.

Most companies that I’ve worked at have just implemented our own on top of the OS syscalls. Which is annoying because it requires at least a Windows and UNIX variant.

Look, I like C++. I’ve been programming in it for years. But some of the stereotypes around C++ programmers are true. I still occasionally run into design decisions so untethered from reality that it still shocks me after all these years.

QFile is mostly fine (it's probably not the fastest, but not slow), and QString is pretty comfy for all kinds of string manipulation :)

C++ has a filesystem API? TIL, never used it.
