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.

No Prerequisite Any one can take CS143 Not any one can pass CS143 D/F rate: 25-40% Recommendation: Previous programming experience such as CS 1130 (Math) (English)
