Core Lower-Division UCR CS Courses: Laying the Foundation

The lower-division sequence at UCR is designed to build a robust programming and mathematical foundation. The primary programming language utilized across these introductory courses is C++, a language chosen for its performance, manual memory management capabilities, and industry relevance. This choice of language ensures that students learn what is happening "under the hood" from their very first quarter.

• CS 010A (Introduction to Computer Science for Science, Mathematics, and Engineering I): This course introduces the fundamental concepts of structured programming. Students learn variable types, control structures, loops, and basic functional decomposition. The course serves as the gatekeeper for the major, requiring rigorous logical thinking.
• CS 010B (Introduction to Computer Science for Science, Mathematics, and Engineering II): Building directly upon CS 010A, this class introduces object-oriented programming (OOP). Topics include classes, pointers, memory allocation, recursion, and basic file input/output. It is highly projects-focused and emphasizes clean code architecture.
• CS 010C (Introduction to Data Structures and Algorithms): The final piece of the introductory trilogy transitions students from basic programming to algorithmic efficiency. Here, students implement foundational data structures such as linked lists, stacks, queues, trees, and hash tables, analyzing their performance using Big-O notation.

Beyond programming, lower-division students must conquer CS 061 (Machine Organization and Assembly Language). This highly demanding course bridges the gap between software and hardware, teaching students LC-3 assembly language, binary representation, and CPU execution cycles. Accompanying these technical tracks is CS 011 / MATH 011 (Discrete Structures), which establishes the formal mathematical logic, set theory, and combinatorics required for advanced algorithmic analysis.

Upper-Division Requirements and Specializations

Once students transition to upper-division status, the academic rigor accelerates significantly. The transition is marked by CS 100 (Software Construction), a crucial milestone course. In CS 100, students work in teams to design and build complex software systems, learning modern development methodologies, design patterns, version control (Git), and unit testing. This course is often cited by alumni as the most practical preparation for software engineering internships.

Following CS 100, students must complete core theory and systems courses:

• CS 111 (Discrete Structures II): A deep dive into formal proofs, graph theory, and recurrence relations.
• CS 141 (Intermediate Data Structures and Algorithms): Focusing on design strategies like divide-and-conquer, greedy algorithms, dynamic programming, and NP-completeness.
• CS 153 (Design of Operating Systems): An intense, systems-level course where students study process management, memory allocation, file systems, and concurrency, often modifying an actual operating system kernel.

In their senior year, students can tailor their degree through specialized electives and the mandatory CS 179 (Project in Computer Science) capstone series. These capstone courses allow students to work in collaborative groups to solve real-world problems in specific domains, such as Artificial Intelligence (CS 179F), Compilers (CS 179E), or Database Systems (CS 179G), providing a portfolio-ready project to showcase to recruiters.
