Compute and Write CSV Example
=============================

The file ``cpp/examples/arrow/compute_and_write_csv_example.cc`` located inside

and then comparing the magnitudes of the entries in the columns and writing out to
a CSV file with the column entries and their comparisons.  The code in the example
is documented.
