The book introduces C languages to implement various data structures in computer science. It starts with explaining the basic concepts of C language, followed by application of those concepts in C programming and ends with a huge number of complete C programs on advanced data structure problems.The book covers all the data types in C with internal implementation and gives examples to demonstrate their behavior. All operators, expressions and rules that evaluate expressions are also explained and exemplified. The book covers all the data structures such as linked lists, trees, graphs, arrays with mostly used algorithms. The book also deals with advanced data structures such as Btrees and B+trees and several advanced problems in data structures.
