Data Structures through C Language

Introduction to Data Structures

  • Data structures are concepts of algorithms used to structure information, not a programming language.
  • We implement these algorithms using programming languages like C, C++, Java, etc.
  • Java has a predefined implementation called Collections Framework.

Importance of Data Storage

  • Data storage is crucial for applications, especially in data science.
  • Early recognition of data importance led to the development of languages like Python for faster data processing.
  • Data analysis has become essential as the importance of data processing is understood.

Definition of Data Structures

  • Data structures are about how to store information effectively using algorithms.
  • Algorithms to manage data structures are known as Abstract Data Types (ADTs).

Examples of Data Structures

  • Common data structures include:
    • Arrays
    • Stacks
    • Queues
    • Linked Lists
    • Trees
    • Graphs
  • Algorithms for sorting and searching also fall under data structures.

Types of Data Structures

  1. Linear Data Structures

    • Elements arranged in a sequential format.
    • Examples: Arrays, Stacks, Queues, Linked Lists.
  2. Nonlinear Data Structures

    • Elements can connect to multiple other elements.
    • Examples: Trees, Graphs.

Arrays

  • Definition: A data structure that holds more than one element of the same type (homogeneous).
  • Properties:
    • Index-based, allowing faster access to elements.
    • Considered a derived data type.
    • Does not follow any specific algorithm.

Accessing Array Elements

  • Example declaration: int A[5];.
  • Memory allocation is continuous; for instance, base address 2046.
  • Accessing A[3] gives the value at that index directly.
  • Involves pointer arithmetic to get values efficiently.

Advantages of Arrays

  • Arrays allow storing multiple elements under a single variable, simplifying data management.
  • Compared to primitive variables (e.g., int a, b;), arrays simplify access patterns and reduce complexity.

Importance of C Language Concepts for Data Structures

  • To implement data structures in C, understanding the following concepts is crucial:
    1. Functions
    2. Recursive Functions
    3. Arrays
    4. Structures
    5. Pointers
    6. Dynamic Memory Allocation

Next Steps

  • The next session will cover implementing the stack algorithm using both static and dynamic memory allocation.
