Functions as required and has appropriate comments in the code Day, date, and all weather outputs formatted as required Git Hub repo updated and shared via Canvas comment if repo other than Activity5 repo created for class.
15 to >8.0 ptsMissing Functionality
One or two values not formatted correctly, are missing (Date, Day, weather values, etc), or some outputs missing identifying text
8 to >0 ptsMissing Functionality
Multiple values not formatted correctly, are missing (Date, Day, weather values, etc), or some outputs missing identifying text

This criterion is linked to a Learning OutcomeException Handling
5 to >4.0 ptsExceptions and Errors Handled and Reported
Program reports errors to user if the city or country name is invalid and allows user to continue

Program does not report errors or user not allowed to continue after entering invalid values
0 ptsMissing Functionality
Program crashes when an invalid city or county is input
