This page contains the programming assignments for this course. Each assignment specification describes the technical requirements. The assignment FAQ contains important information common to all assignments.
Grading. Programming assignments are worth 35% of your total course grade: 7% for completion credit (submitting code that compiles by the deadline) and 28% for code review credit (demonstrating your understanding in a code review with a TA). The autograder is for feedback only—it does not determine your grade. See the assignment FAQ and the course policies for more details.
Submission. Submit your solutions via TigerFile using your Princeton NetID. Assignments are "due" at 11:59pm ET on Monday evenings (for the completion grade).
