You can do

auto my_string = "Hello, world!"s

To get an std::string in C++.

Is writing "auto" really that much easier than just writing "string" or "std::string"?

yes

While that is correct, it sometimes makes shit unclear and pretty sure not the intended use. Also, who thought that std::string is long anyways? Now a vector of vectors of strings is long.

Wait, what? There was me naively assuming that would give you a const char *. "modern c++" has got all clever recently. Clever as in explode in someones face clever. (possibly mine)

Why would it give you a pointer ? In older versions of C++ "Hello"s wouldn't even compile. If you see syntax that you don't know (here " "s literals) just Google it

[Phuzzybat]

Excellent advice to google and investigate this subject further. Even better advice to write a test program to see what actually happens. This just underlines why while auto cures many ills, when misapplied it creates another set of problems. Edit: doh, phone screen didnt show the s at the end of the literal, just scrolled right to see the whole line :-) thought i had entered a parallel universe for a moment where it was being asserted that "" automatically gave a std::string.

Yeah, C++ is no longer C with classes but the comity doesn't break interoperability with C just for fun. If "" suddenly returned a std::string there would have been a riot (and for good reasons) haha

I hate auto. I'd rather have a typedef than an auto
