Hi, there,
My task is:
There is a network of intersected lines, e.g., a road network. What I
have is a list of lines, and each item in the list includes the
coordinates of points on each line.
I need an algorithm to trace the whole network, find the intersections
of all the lines, and record the lengths between two different
intersections or between an intersection and an endpoint of a line. Can
you help me out to design an efficient algorithm to do this? Any
suggestaions on the algorithms and data structures would be highly
appreciated. If you could write it in pseudo-code, that would be even
better.
Thanks a lot,
JJ 3 1833

The place for this question is more likely comp.programmin g. I
have added follow-up to it.

I think an algebra text should have all the information you need.
Note that this newsgroup is not about algorithms, but the ISO
standard C language. Once you've located or devised an algorithm,
you can translate it to C. If you need help with the C code, then
post the pertinent portions and we'll try to help.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
