HW7: Count A

The purpus of this program is to count the number of occurences of each character in a file.

The program will read a file and then give the output by standard out. The output is a table of the ASC II codes, the corresponding characters (and symbols if printable) and their counts followed by two spaces. Each code is printed in anew line. Only the characters that appear in the file are printed on screen.

The program is tested against the following test files: CountATest1, CountATest2, CountATest3, Alice, and Science.  The last two are the download novels from the online Gutenburg project. The running time is computed. It seems the program runs very very fast.
