Reads an unspecified number of sorted values from a file specified by the user, and displays the median value (The median is the middle number when the numbers are sorted by size.), average value, and how many numbers were read. (Note: Do not use an array.)

Using the pseudocode developed in the last exercise, write the program in these two steps:

Step 1: Write a shell program that implements stub functions demonstrating that your function calls work. (Simple cout statements in functions.)

Step 2: Fill in the code and complete the program

Documented source code with shell and stub functions for Step 1.

Documented source code for completed program in Step 2.

Code down below is the code from previous to build on.
