Data Structure is a central course in the curriculum of all Computer Science programs. The book ‘Data Structures and Algorithms Using C’ aims at helping students develop programming and algorithm analysis skills simultaneously so that they can design programs with the maximum amount of efficiency. The book uses C language since it allows basic data structures to be implemented in a variety of ways. This book follows the syllabus of Data Structures and Algorithms course being taught in B Tech, BCA and MCA programs of all institutes under most universities.
