Overview

This course teaches imperative programming and methods for ensuring the correctness of programs. It is intended for students with a basic understanding of programming (variables, expressions, loops, arrays, functions). Students will learn the process and concepts needed to go from high-level descriptions of algorithms to correct imperative implementations, with specific applications to basic data structures and algorithms. Much of the course will be conducted in a subset of C amenable to verification, with a transition to full C near the end.

Either 21-127 or 15-151 is a co-requisite (must be taken before or in the same semester). This course prepares students for 15-213 and 15-210.

More information about the course objectives can be found in the syllabus.

Grading

The course is graded on a 1000-point scale. Absent exceptional circumstances, scores of 900 and above will be given an A, scores of 800 and above will be given a B, etc. Scores below these thresholds may receive the higher grade based on participation and/or exam performance on the sole discretion of the instructor.

• Exams 50% Two 125-point midterms and a 250-point final
• Homework 40%
  • written assignments
  • one-week programming assignments
  • 2 two-week programming assignments with a checkpoint
• Labs and Quizzes 10% Labs and quizzes are mostly for your own improvement, but they will be given a small number of points. The lowest three quiz grades and the lowest 2 lab grades will be dropped.

Style re-grading can be done by any TA. All other grading disputes or requests for re-grading should (policy TBA).
