In the earlier chapters we have seen the primitive data structures that are available in c. Most books attempt to teach it using algorithms rather than complete working programs a lot is left to the imagination of the reader, instead of explaining it in detail. The book utilizes a systematic approach wherein the design of each of the data structures is followed by algorithms of different operations that can be performed on them, and the analysis of these algorithms in terms of their running times. In other words, a data structure defines a way of organizing all data items that consider not only the elements stored but also their relationship to each other. Before solving a problem, a major decision is taken about which data structure will be used to represent the data.
