making a simulation in c++

hello,

I'm a traffic engineering student. I have basic knowledge of c++ and little about advanced concepts (say, classes, composition & inheritance etc). anyone kindly answer me what i should know before go for making a simulation in c++ ?? say, I would like to simulate this dual-ring controller -

Well, if you can use and apply them, you're set.

But the nature of your question says that you can't.
Try reading up on a bit on OOP theory and program design
....and make some simpler programs first. (this appears to be simple enough, though.)

thanks for your answer. any advice how to start graphical things in c++ ? say,making a GUI that will show your simulation.

The GUI should, ideally, be the last thing you should think about, when doing such things.
Try any of the cross-platform C++ toolkits.. (Qt, Gtkmm, fltk..etc) or a graphics library like SFML or SDL( or even raw OpenGL or Direct3d if you can manage it. )
Mixing one or more of the above will be necessary, depending on what you want to show.

I'd suggest that you forget about the GUI now and design the back end of the simulation.

manasij7479 is spot on.

The GUI is just presentation; without the simulation working you have nothing to present.
