I’m trying to output a simple unique point using the unique\_ptr class and keep getting this error shown in the screen shot below. Any idea why?

I ran your code. It works perfectly fine on my IDE.

`operator<<` for `unique_ptr` was overloaded in C++20 language standard. So change your language standard as shown [here](https://code.visualstudio.com/docs/cpp/config-msvc#:~:text=You%20can%20view%20the%20C,json%20in%20the%20.vscode%20folder.).

Change `"cppStandard": "c++17"` to `"cppStandard": "c++20"`.

You can explore libraries and classes updates with standards on [C++ reference](https://en.cppreference.com/). Though it is sometimes hard to see through the error, as many tutorials use older versions of C++ and we assume existence of a feature or function that has not yet been implemented (or was removed).
