return 0;
}

this is my code for my assignment, my professor said i'm missing

Based on that rubric, it looks like the code is missing two things:
* Person class in separate files

* Output persons with user-entered gender works for "any"

can someone help me with this?

Expert Solution

HI Friend, I have separated code in seperate files.

Please let me know in case of any issue.
