Writing a range-for loop in a container on Microsoft visual studios 2022

[Ostronomos]

I am struggling to make a successful attempt at transferring code involving a vector of strings that uses a range-for and an iterator to output paragraphs of information (aka strings) but the MVStudios 2022 is saying that I do not have the preprocessor variable correct even though I am using #define. What, am I doing wrong? And why doesn't the book translate to the program?

Is there a "#" in verbatim string? If so, that could be where the preprocessor error is coming from, and you can concatenate the string to avoid it.
