Loop over values of f, compute c, print as table with headings. The slightly simpler feet to meters conversion was the first program I ever wrote.
Recreated in coffeescript:
console.log "F\tC" for f in [0..100] by 5 c = 5/9*(f-32) console.log "#{f}\t#{c.toFixed 2}"
Produces this output:
F C 0 -17.78 5 -15.00 10 -12.22 15 -9.44 20 -6.67 25 -3.89 30 -1.11 35 1.67 40 4.44 45 7.22 50 10.00 55 12.78 60 15.56 65 18.33 70 21.11 75 23.89 80 26.67 85 29.44 90 32.22 95 35.00 100 37.78
