  Contract: main: void -> int

  Purpose: provides an example comparing opening a file for
           writing, as compared to opening a file for appending;
           ask the users for an integer and 2 file names, one to 
           which to write the integer and one to which to append
           the integer.
  
  Examples: Assume that file1.txt in the current working directory
            contains:
I am file1.txt.
            ...and that file2.txt in the current working directory
            contains:
I am file2.txt.

           Then, if the user now runs the program two_writes, if he/she
           responds when prompted with:
1326
file1.txt
file2.txt
           ...then after this program is done file1.txt contains:
1326
           and file2.txt contains:
I am file2.txt.
