Accessing elements of const pass by reference std::list
What would be the proper way to access elements that are passed by const reference? Specifically std::list. ex. const std::list<std::string>& someStrings
I understand that it is a reference to memory and that it cannot be modified, but how would I copy values to new string variables or print out the contents of the list.

You use the list as normal. You can use iterators or range-based for loops to access the elements.
When an object is pass as const reference it means that you can use functions that are marked as const only.
E.g
So copy things from that object is usually possible. I.e. you can copy the elements of the list without problems.
