// Lab #8: File It Away
// Program: READCHAR.CPP

// This program reads all of the character values in
// a user-specified file, and simply writes them back
// to the screen in the same format.

// Note the use of a slightly different strategy for
// testing for the end of each line and the end-of-file
// marker.
// This is possible because we are reading for characters
// this time, not integers.

// Your task is to modify this code so that it counts
// the number of lines and the number of 'e's in the
// input file.  READ THE COMMENTS CAREFULLY.  Understand
// what this basic skeleton is doing before you try to
// modify it.
