Now a day, getting good job in IT companies everyone should be excellent in programming. C language is known as very good and middle level programming language in the industry. Data structures are one of the most significant parts of the programming. The main objective of this course is to give fundamental knowledge about linear data structures and non-linear data structures which will help them to implement the actual data structures and their ideas as an application. This course will cover all the basic data structures and their applications. In this course the working principles of linear data structures such as arrays, linked lists, stacks, queues, trees and graphs will be discussed. All this discussion will be with respect to C language. After successfully completion of this course student will be able to understand the basics and way of implementation of the data structures as well as the applications of these data structures. The students will be able to select the appropriate data structures for the specified application. Selection of proper data structures reduces the complexity of the coding and provides simpler way for software development. All these data structures can be implemented in various programming languages very easily. This course is open for all the students.
