This course gives a solid understanding of the principles and abstractions used in computer systems and machine programs using C. Towards this aim, it covers a broad range of topics, providing students with an in-depth perspective and programming experience regarding the basic topics of C language and how programs are formed and executed at the microprocessor-level.
Upon the completion of COMP201, student will be able to (1) demonstrate proficiency in writing C programs that require effective memory management, (2) gain a deep knowledge of the compilation flow and runtime behavior of C programs, (3) have a clear understanding of computer arithmetic in a modern computing system, (4) recognize the relationship between a C program and its assembly translation, and (5) gain a general sense of working in a Unix environment as a power user, getting familiar with shell tools, version control systems, compilers, debuggers, profilers.
The course is taught by Aykut Erdem, Osman Batur Ince, Doga Kukul, Yusuf Bayindir, Muhammed Burak Kizil, Idil Gorgulu, Atalay Görgün, Eda Güven, Mehmet Harmanli, Tufan Kivanc Kurt.
Lectures: Monday, Wednesday at 13:00-14:10 (SNA A52)
Labs: Friday at 14:00-15:40 (Lab A) (SNA B242), 16:00-17:40 (Lab B) (SNA B149)
Office Hours Mondays at 17:30-18:30 (Aykut)
Policies: All work on assignments must be done individually unless stated otherwise. You are encouraged to discuss with your classmates about the given assignments, but these discussions should be carried out in an abstract way. That is, discussions related to a particular solution to a specific problem (either in actual code or in the pseudocode) will not be tolerated.
In short, turning in someone else’s work, in whole or in part, as your own will be considered as a violation of academic integrity. Please note that the former condition also holds for the material found on the web as everything on the web has been written by someone else.
The course webpage will be updated regularly throughout the semester with lecture notes, presentations, assignments and important deadlines. All other course related communications will be carried out through Blackboard.
COMP201 is open to second-year undergraduate students. Non-COMP students should ask the course instructor for approval before the add/drop period. The prerequisites for this course is COMP 132 - Advanced Programming.
Grading will be based on
