Wow, strongly disagree on this David.

I have a c++ class in my windows code called CsvString. It is designed
to contain a string of comma seperated values.  Here is some code that
uses that class:
  CsvString  line ;
  line << "value1" ;
  line << "value2" ;
  line << 55 ;

that code adds three values to the comma seperated values string.  

Another class represents a text file in the file system. could easily
be a file you would write to the IFS.  Here is code that writes the
comma sep value string to the text file:
  TextFile orders ;
  orders.OpenNew( "c:\\directory\\filename.txt" ) ;
  orders << line ;

that is it.  the destructor of the TextFile class automatically closes
the file when class instance goes out of scope.

C++ can be the most readable language for business applications
available.  It all depends on how you use its features.
