Data is an essential part of our daily lives. Organizing and storing data is very important. Data is stored in various ways and formats. It can be either a single set of values or multiple values. A data item refers to a single set of values in general. Data structure stores and organizes a large set of data in computer memory. It ensures the re usability of data efficiently later. Data can be stored logically or mathematically. It can vary depending on the organizational needs and adaptability levels. A data structure is a framework that has been carefully designed to organize, process, retrieve, and store data. To organize data for certain purposes, both simple and complex data structures are devised. Users find it simple to obtain the data they need and use it appropriately thanks to data structures. Data structures help both machines and people to understand how information is organized. This lecture was organized for BCA-II year students. Dr. Anuradha Chug Associate Professor, USICT, GGSIP University, Delhi was the Resource person and expert for the Data Structure C & C++ Programming. She demonstrated different types of graphs generation and data representation . She gave the idea about how the data structure applications are useful in our daily routine work. The motive behind this lecture was to give the expose the students to the topic “Data Structure and its Application using C & C++”. The session aimed at providing the knowledge of Data Structure Applications and how the data structure is connected to our real life. They learned the basic concept and use of the applications of data structure.
