CS143: Course Outcomes
Upon completion of this course, students should be able to:
• Develop algorithms to solve "computer-solvable" problems. • Test algorithms. • Translate algorithms to C++ programs. • Debug, run and test C++ "procedural" programs. • Understand the software development process by using
requirements to design, implement and test C++ programs.
