wheres my mistake?

Create an application that will accept values from a user and when the user has completed the submission of the values a sentinel value will be input, then the application will display the array as it was input and then sort the array and display the sorted array.

Here is an example of what I/O would look like:

Enter the values to be sorted (Type X when done):

20 89 6 4 33 X

The 5 values entered are:

20 89 6 4 33

The 5 sorted values are:

4 6 20 33 89
