I am presently learning c and c++.I find problems with linked lists and related topics.Can anyone suggest me the ideas to make them easy.

The trick to learning is to just keep working with things over and over until they begin to make sense. I wouldn't expect anyone (certainly not myself ;)) to understand even a simple programming concept right away, especially if they don't have a good point of reference to relate to it.

>Can anyone suggest me the ideas to make them easy.
The ideas that make programming easy are derived from your experiences and built up gradually as you learn. They're very personal, and an idea that simplifies things for you won't necessarily do the same for someone else. Of course, by the time you have the simple ideas, you don't really need them anymore. Such is life.
