  1. /*The attached file is a historical record of BCS courses offered over the last four semesters.  An X in one of the first four columns indicates that the course was offered in the semester that heads the column.  A period (.) indicates that the course was not offered in that semester.
  2.  
  3. Read the file and store the following information in two vectors:
  4.  
  5. An integer that encodes the semester offerings for the course as follows; Fall 15 counts 8, Spring 16 counts 4, Fall 16 counts 2, and Spring 17 counts 1.  The offering code is the sum of these four numbers.
  6. A string which saves the course number and title that follows after the four offering columns.
  7. The two vectors are parallel in the sense that a given subscript selects offering information and the description for the same course.  E.g the subscript 0 selects offering information and the description for the first course in the file.
  8.  
  9. After reading, encoding and saving all the course information, display the number of courses read.  Then list on cout
