Computer Science at TJHSSThttp://www.tjhsst.edu/compsci• Introduction to Computer Science

– A mandatory course for all TJ students, the intro. course assumes no prior programming experience. Students study object-oriented programming and develop fundamental programming skill. In preparation for the AP course, Java is the language of instruction.

10

Computer Science at TJHSSThttp://www.tjhsst.edu/compsci• AP Computer Science

– An elective course available to all students who have completed Introduction to Computer Science, APCS follows the College Board topic outline. This course carries an additional 0.5 quality point in GPA calculation and pepares students to take the APCS Exam given each May.

11

• Accelerated Computer Science– A non-traditional route designed for

experienced programmers only, this course requires exceptional problem solving skills (by TJ standards).

12

Computer Science at TJHSSThttp://www.tjhsst.edu/compsci• Summer School

– How better to spend five weeks of summer than learning Computer Science with 140 of your closest TJ friends. A great way to fit more into your cramped schedule, the summer school program thrives because of students aides (upperclassmen, apply early). An accelerated class is usually formed during the second week. Not only is there an ice cream social and a pizza party, but you may even get to work with teachers from outside TJ.

19

Comparative Languages

• Evolution of programming languages• Syntax and semantics representation• Machine parsing of grammars, building a

compiler • Some issues: Exception handling,

Concurrency, Garbage collection• Language approaches: imperative, object

oriented, functional, logic based

20

Comparative Languages• Scheme

– functional programming language and a dialect of Lisp. It was developed in the 1970s, MIT. Lisp, 1958, is the second-oldest high-level programming language in widespread use today; only Fortran is older.

• Smalltalk – object oriented programming language designed at

Xerox PARC (Xerox Palo Alto Research Center) by Alan Kay and others during the 1970s...great influence on the development of many other computer languages

21

Comparative Languages• Prolog

– Programmation en logique (French for "logic programming"), created by Alain Colmerauer around 1972 to make a programming language enabling the expression of logic instead of specified instructions on the computer.

• ML– functional programming language developed by

Robin Milner and others in the late 1970s at Edinburgh University. CMU

22

Comparative Languages• C programming language

– low-level standardized programming language developed in the early 1970s by Ken Thompson and Dennis Ritchie for use on the UNIX operating system.

• Fortran– compiled, programming language originally

developed in the 1950s and still heavily used for scientific computing and numerical computation half a century later.

23

Comparative Languages• Python

– interpreted, interactive programming language created by Guido van Rossum in 1990. Used in our AI course.

• Ruby – object-oriented language, combines syntax

inspired by Ada and Perl with Smalltalk-like features, also shares some features with Python, Lisp. Ruby's an interpreted language created by Yukihiro "Matz" Matsumoto, began working on Ruby on February 24, 1993 and released to the public in 1995.
