Menu: Difference between revisions

* Print a textual menu formatted as an index value followed by its corresponding string for each item in the list.

* Prompt the user to enter a number.

 

The function should reject input that is not an integer or is an out of range integer index by recreating the whole menu before asking again for a number. The function should return an empty string if called with an empty list.
