Data Structures In C Pdf | Data Structures Syllabus

The objectives of this course are to:

  • Introduce the basic concepts of data structures and abstract data types
  • Stress the importance of data structures in creating and implementing efficient algorithms
  • Explain how data structures, such as arrays, records, linked systems, stacks, queues, trees, and graphs, are represented in memory and utilized by algorithms.

Upon completing this course, students will be able to:

  • Understand the properties, interfaces, and behaviours of basic abstract data types
  • Analyze the computational efficiency of the main algorithms for sorting and searching
  • Utilize arrays, records, linked structures, stacks, queues, trees, and graphs in programming
  • Apply various methods for traversing trees.


  • Definition and classification of data structures
  • Operations on data structures
  • Abstract data types (ADT)
  • Introduction to algorithms, including time and space complexity
  • Searching algorithms: linear search, binary search, Fibonacci search
  • Sorting algorithms: insertion sort, selection sort, exchange (bubble sort, quick sort), distribution (radix sort), and merging (merge sort) algorithms.
