• Programming Problem #12 of Chap. #4 on pg. 162 of the textbook.
  
  
• For the following three test input data files:
  
  
  1. Test input datafile1
     
     
  2. Test input datafile2
     
     
  3. Test input datafile3
     
     

  For each input test datafile be sure to include in your source file the expected results as a comment at the end of the code. Please see example Template file for more details.

Hint: your programming solution should take as input the datafiles and produce output in the format specified by the original problem statement.
