jolonb / clockangle

A small C script for calculating the angle between the hour hands of two superimposed clocks

Clock Angle

Have you ever wondered what the angle between the hour hands on a clock is at two different times?
Me neither, but here it is anyway.

Simply provide two times in the format hh:mm:ss and the program will calculate the angle between the hour hands.
Or if you're feeling fancy, you can just give one time in the same format as above. This will tell the program that you want to know the angle between the minute and the hour hand.

Running

Compile with

gcc clockangle.c -o clockangle

To debug, use

gcc clockangle.c -o clockangle -DDEBUG

Hour Hands

To find the minimum angle between the hour hands on two superimposed clocks, run the program with:

./clockangle h1:m1:s1 h2:m2:s2

For example:

./clockangle 2:06:52 19:43:08

The program will return the minimum angle between the two hour hands.

Minute/Hour Hands

To find the minimum angle between the hour and minute hand on one clock, run the program with:

./clockangle h:m:s

For example:

./clockangle 06:46:45

clockangle's Issues

Make it work for a single clock

Rather than just calculating the angle between the hours hands of two clocks, this program could also have the option to have only one input argument and it will calculate the angle between the hour and minute hands
