Lesson 15. Capstone: Temperature tables

Write a program that displays temperature conversion tables. The tables should use equals signs (=) and pipes (|) to draw lines, with a header section:

=======================
| °C       | °F       |
=======================
| -40.0    | -40.0    |
| ...      | ...      |
=======================

The program should draw two tables. The first table has two columns, with °C in the first column and °F in the second column. Loop from –40° C through 100° C in steps of 5° using the temperature conversion methods from lesson 13 to fill in both columns.

After completing one table, implement a second table with the columns reversed, converting from °F to °C.

Drawing lines and padding values is code you can reuse for any data that needs to be displayed in a two-column table. Use functions to separate the table drawing code from the code that calculates the temperatures for each row.

Implement a drawTable function that takes a first-class function as a parameter and calls it to get data for each row drawn. Passing a different function to drawTable should result in different data being displayed.
