CS 125

Basic concepts in computing and fundamental techniques for solving computational problems. Intended as a first course for computer science majors and others with a deep interest in computing. Course Information: Credit is not given for both CS 125 and CS 124. Prerequisite: Three years of high school mathematics or MATH 112. Class Schedule Information: Students must register for one lab-discussion and one lecture section. Engineering students must obtain a dean's approval to drop this course after the second week of instruction.

1. Create computer programs that solve a variety of problems using appropriate techniques, including imperative, recursive, and object-oriented approaches. (1, 2, 6)
2. Read and understand iterative and recursive computer code—determining intention, tracing runtime behavior, identifying bugs and errors that might occur, and estimating computational cost and complexity. (2)
3. Develop and debug programs using industry-standard tools and best practices, including visual editing and debugging (IntelliJ and Android Studio), source version control (Git), and pair programming. (1, 2, 5, 6)
4. Understand the features of computers that make them useful for solving problems, including computation, memory, storage, and networking. (2)
5. Learn and apply classic computer science algorithms for sorting and searching data while understanding their behavior and running time. (1, 6)
6. Write computer programs that represent and manipulate different types of information—such as text, audio, and visual data. (1, 2, 6)
7. Formulate useful algorithms that solve real problems and can be implemented and run on a computer. (1)
8. Use object-oriented design to appropriately structure data and couple data and behavior. (2, 6)
