** Name: 

** Filename: ASCII.cpp

** Project #: Deitel & Deitel 11.17

** Project Description: Write a program that uses a for
   structure to print a table of ASCII values for the 
   characters in the ASCII character set from 33 to 126.
   The program should print the decimal value, octal 
   value, hexadecimal value and character value for each
   character. Use the stream manipulators dec, oct and hex
   to print the integer values. Also send output to a 
   datafile as well as to the screen.

** Output: List of ASCII character set from 33 to 126
             -List sent to screen output
	     -List sent to data file "outputfile.txt"

** Input: None

** Algorithm: Instruct the user on the purpose of program
              Make file outputfile.txt to send information to
	      Do a for loop for values 33 to 126
		print out the decimal /send to file
	        print out the octal /send to file
	        print out the hexadecimal /send to file
	        print out the character /send to file
	      Once all values from 33 to 126 have been printed
	      Exit program

Program Output

This program will print a table of ASCII values for ASCII character set
33 to 126 on the screen. At the same time it will send information from
the program and print the same table in the datafile <outputfile.txt>.
