algorithm question

[minnew]

I looking to design a (graphical) program in which a known path (such as anelectrical circuit) can be interrupted by the user. That is, the user canclick the mouse anywhere on a path to "cut" it so that the path is disabled. Once the path is cut, the item connected to the path reacts (such as a light bulb going out). From a high level point of view, what would be the best code / algorithm to design such an interface?

thanks

Sorry, I think you're in a wrong newsgroup. Here we talk C++
*language*. If you have a C++ language problem, post it. If you don't
know where to begin, there are better places to ask about it than here.
Perhaps you should look at comp.programming or some physics
(electricity) newsgroup...

The standard library of C++ does not allow the UI of such a
program to be written. One needs to employ an additional GUI
framework or library. The design of the UI code then follows
the choice of a library. It cannot be designed upfront.

An algorithm always depends on the operations available. When
they are not know, one cannot write an algorithm.

Having said this, it always helps to know MVC when one wants
to write a GUI program:

, and usually one can best design a GUI application after
having gained experience with several small toy problems
in GUI programming, i.e., simple exercises.
