difficulty in understanding how pointers work in c

Question

I am learning c language for over a year now. But I still don't understand how pointers work. Can anyone suggest a good online resource to make concepts clear.

There is vast number of sources regarding C pointers. You can google for it. Try to read a few, one of them may just click.

Answer 2

If you are clear with your concepts of pointers in one language, it would mean that you are clear in all possible programming languages as it is one of the most fundamental concepts.
