Course Description

This course is concerned with the concepts and practice of programming languages. The first part of the course will focus on general programming language concepts such as binding, type checking, and memory management. The implementation of these concepts in different languages will be examined, with special attention paid to Java and C/C++. The second part of the course will focus on different programming paradigms: procedural, object-oriented, and functional programming. Java, C++, and JavaScript will be studied as hybrid languages, combining both procedural and object-oriented features with varying design goals. Scheme will be studied as an example of a completely different programming paradigm, one which focuses on functional composition as opposed to state transformation or object interaction. In addition, groups of 2-3 students will each research and present an overview of a modern scripting language (e.g., perl, php, python, ruby, R, scala).

The specific goals of this course are:

Course Structure

This course is considered by the university to be an In-person Instruction (SD100) course. The classroom allows for all students to attend class in person while maintaining appropriate social distancing. If you must miss a class because of an emergency, you are expected to notify the instructor as soon as possible. If you are sick, please do not come to class. In the event of illness (fever/chills, shortness of breath, headache, sore throat, lack of taste/smell, etc.) please register your condition with the COVID-19 Screening App CampusClear and notify the instructor. Classes may be streamed on zoom or recorded upon request so you won't fall behind. Be aware that all class materials posted on Blueline, including quizzes, discussions, and Zoom recordings, are considered to be copyrighted and are intended to be used only by students enrolled in the class, for the purposes of fulfilling the course objectives. Only the instructor may record common class sessions. Sharing any of these materials with others outside of the course will be considered "misuse of academic resources," as defined in the Creighton University Student Handbook as an act of academic misconduct, and students can be penalized, up to and including failure of the course.

Students in this course will adhere to all Creighton community standards. Students will properly wear a mask in class and maintain 6-feet of distance between individuals whenever possible. Students will be required to enter and leave classrooms in a socially distant manner. For this reason, the instructor will plan to dismiss you in sections. You are required to sanitize your work area upon arrival and departure with the provided supplies.

Instructor office hours will be conducted via Zoom, with face-to-face (but socially distanced) meetings scheduled by request.

Required Work

There will be 5-7 homework assignments, most of which will involve programming. Assignments will be submitted electronically via the class BlueLine site and will be due at midnight on the date specified. Late assignments will receive 75% of full credit if they are handed in within one week of the specified due date. After one week, no credit will be given. The group project will involve researching a modern scripting language and giving a 20-minute presentation on that language to the class. In addition, there will be 6-8 module quizzes (with the lowest quiz grade dropped), a midterm exam and a cumulative final exam. Grades will be determined as follows:

homework assignments 40 %
group project/presentation 10 %
module quizzes 05 %
midterm exam 20 %
(cumulative) final exam 25 %

At the minimum, departmental grading cutoffs for the final average will apply. That is, 93-100% guarantees an A, 90-92% an A-, 87-89% a B+, 83-86% a B, 80-82% a B-, 77-79% a C+, 73-76% a C, 70-72% a C- and 60-70% a D. Depending on class performance, some shifting of grades (in an upward direction only) may occur as final letter grades are assigned.

Regular attendance is expected of all students. If you must miss class for a legitimate reason, it is your responsibility to make up missed work. Quizzes and Assignments will not be rescheduled except in extreme circumstances. It is expected that all students check their Creighton email accounts regularly. Official announcements, such as assignment revisions or class cancellations, will be distributed through Creighton email.

Policy on Collaboration

Creighton's policy on cheating and plagiarism is spelled out in the Student Handbook, with college procedures available online. In addition to this, the following guidelines hold pertaining to programs. Programs are to be the sole work of the student -- collaboration on the design or coding of a program is not allowed. Questions regarding homework assignments should be directed at the instructor only. Students may seek debugging assistance or clarifications on assignments via the class mailing list (accessible via BlueLine). Repeat: All student interactions regarding homework assignments must take place via email to the entire class!

Violations of this policy will be dealt with severely, with possible outcomes including failure in the course. In the case of programming assignments, you are encouraged to start early so that there is time to seek help from the instructor as the need arises.

Sample code from the lectures

Creighton University may modify, suspend, or postpone any and all activities and services immediately and without notice because of force majeure causes beyond Creighton's control and occurring without its fault or negligence including, but not limited to, acts of god, fire, war, governmental action, terrorism, epidemic, pandemic, weather, national emergencies, or other threats to the safety of students or staff. Creighton may, at its option, alter the academic schedule or provide alternate instruction modalities to meet course objectives and competencies and program outcomes, including, but not limited to, distance or remote learning, until such time as Creighton determines normal operations may resume safely.
