/* ******************************************************************************
* ExamStatisticsProgram
*
* This program is designed to compute statistics on a list of exam scores read
* from a text file in response to a console prompt. The console program
* welcomes the user and asks for the name of the text file to input. The text
* file contains the number of scores followed by the list of scores. The
* program then computes and displays the following information to the console:
*
* The number of scores The minimum, maximum, and average scores The number of
* A, B, C, D, and F; using a 90-80-70-60 scale The median of the
* scores.
