What This Document Is
This document is a past examination for CS 225 Data Structures and Software Principles, offered at the University of Illinois at Urbana-Champaign. Specifically, it represents the first midterm exam administered during the Spring 2009 semester. It’s designed to assess understanding of fundamental concepts covered in the early stages of a data structures course. The exam format includes multiple-choice questions and coding problems, mirroring the types of assessments students can expect in this rigorous course.
Why This Document Matters
This resource is invaluable for students currently enrolled in, or preparing to take, a similar data structures course. It provides a realistic gauge of the exam style, difficulty level, and the types of questions asked by instructors teaching this subject. Utilizing past exams is a proven strategy for effective exam preparation, allowing students to identify knowledge gaps and refine their problem-solving skills. It’s particularly useful for self-assessment and practice under timed conditions, simulating the actual exam environment.
Topics Covered
* Pointer manipulation and memory management
* Parameter passing techniques in C++ (by value, by pointer, by reference)
