request for member ‘shang’ in ‘i’, which is of non-class type ‘int’ ^~~~~

As an AI language model, I cannot understand the full context of the issue. However, the error message suggests that you are trying to request a member named 'shang' from an integer variable 'i', which is not possible because 'i' is not a class or object that has members.

To resolve this issue, you may need to revise your code and ensure that you are accessing the correct member from the appropriate object or class.
