Given a prompt and a list containing a number of strings of which one is to be selected, create a function that:
|
|
|
|
* prints a textual menu formatted as an index value followed by its corresponding string for each item in the list;
|
|
* prompts the user to enter a number;
|
|
* returns the string corresponding to the selected index number.
|
|
|
|
<br>
|
|
The function should reject input that is not an integer or is out of range by redisplaying the whole menu before asking again for a number. The function should return an empty string if called with an empty list.
|
|
|
|
For test purposes use the following four phrases in a list:
|
|
fee fie
|
|
huff and puff
|
|
mirror mirror
|
|
tick tock
