I have an error, though I'm doing it like at lesson

[Mark]

How can I fix this, is it because I’m not using clion?

I am rusty on c++ but I think you need to add #include <string> . When I test the code, Main should not be capitalized as well. I am using another software though, visual is buggy for me.
