Data Structures with C# Textbook Exam Questions
Course Introduction
This course provides a comprehensive introduction to the fundamental concepts of data structures using the C# programming language. Students will explore essential data structures such as arrays, linked lists, stacks, queues, trees, and hash tables, learning how to implement and manipulate them efficiently in C#. The course covers the principles of algorithm analysis, memory management, and object-oriented programming techniques as they relate to data structures. Through hands-on programming assignments and projects, students will develop skills in selecting appropriate data structures to solve computational problems and enhance application performance.
