Reads an unspecified number of integers from a sorted file of integers. The file name will be entered by the user. The program will display the following information:

How many numbers were read

The total sum of the numbers read

The average of the numbers read

The median value of the numbers read (The median is the middle number when the numbers are sorted by size.)
