# Print out the table of temperatures
# By CS111

# Better to calculate the temperature conversions 
# but that's not the focus today

# Suggested process: 
# 1. figure out the format specifier for each column.
#    - determine the type
#    - determine the width
#    - determine the flags and/or precision
# 2. fill in the values into each of those columns.

# Note how the column headers are based on the content of the tables

# display the headers
