CSCD 240 — C and Unix Programming

Introduction to C programming in a Unix environment. Topics include C syntax, data types, pointers, arrays, strings, memory management, file I/O, and introduction to systems programming. Emphasis on Unix shell, utilities, and the software development toolchain.

ABET student outcomes

Student outcomes defined by the ABET Computing Accreditation Commission. Outcome 7 applies to cybersecurity-designated programs.

• ABET 1 strong Analyze a complex computing problem and apply principles of computing and other relevant disciplines to identify solutions.
  Analyzes Unix and C problems using computing principles.
• ABET 2 strong Design, implement, and evaluate a computing-based solution to meet a given set of computing requirements in the context of the program's discipline.
  Designs and implements C programs in a Unix environment.
• ABET 6 strong Apply computer science theory and software development fundamentals to produce computing-based solutions. (Computer Science only.)
  Applies software development fundamentals and CS theory (pointer model, process model).
• ABET 7 partial Apply security principles and practices to maintain operations in the presence of risks and threats. (Cybersecurity / Cyber Operations only.)
  Introduces security-relevant topics: permissions, process isolation, input validation.
