My first C program, from 1988.

A program to compute meter gear lengths for a bicycle.

Syntax: bike -f TEETHCOUNTS... -b TEETHCOUNTS... [-d INCHDIAM | -m METERDIAM ]

Example: ./bike -f 24 44 58 -r 13 14 15 16 18 24 -d 27

Output: 

Front sprockets:   24 44 58.
 Back sprockets:   13 14 15 16 18 24.
27.00 inch wheel,  0.686m diameter,  2.15m circumference.
