What this course is NOT about

Learning to program in [insert language here]

but this course should make it easier to learn new languages

Learning tiny bits about lots of different languages

but we will use examples from many languages to examine more

general principles

What this course is NOT about

Learning to program in [insert language here]

but this course should make it easier to learn new languages

Learning tiny bits about lots of different languages

but we will use examples from many languages to examine more

general principles “Language wars” (“Which is better, Java or C++?”)

but you will learn about criteria that can be used to compare

different languages

What this course is about

How are languages designed and implemented?

Specifying syntax and semantics, compiled vs. interpreted, etc.

SLIDE 6

What this course is about

How are languages designed and implemented?

Specifying syntax and semantics, compiled vs. interpreted, etc.

How do such choices affect ease of use, efficiency, scalability, and

ther criteria?
Example: How should recursive calls be implemented? How does

“garbage collection” work?

What this course is about

How are languages designed and implemented?

Specifying syntax and semantics, compiled vs. interpreted, etc.

How do such choices affect ease of use, efficiency, scalability, and

ther criteria?
Example: How should recursive calls be implemented? How does

“garbage collection” work? What are the different programming paradigms?

Example: Why would anyone ever use a language like ML rather

than C++ or Java?

SLIDE 11

Why Study Programming Languages?

Help you choose a language. Make it easier to learn new languages. Help you make better use of whatever language you use.

Language Evaluation Criteria

Readability: the ease with which programs can be read and understood

SLIDE 17

Language Evaluation Criteria

Readability: the ease with which programs can be read and understood Writability: the ease with which a language can be used to create programs

Language Evaluation Criteria

Readability: the ease with which programs can be read and understood Writability: the ease with which a language can be used to create programs Reliability: conformance to specifications

Language Evaluation Criteria

Readability: the ease with which programs can be read and understood Writability: the ease with which a language can be used to create programs Reliability: conformance to specifications Cost: the ultimate total cost

Art of Programming Language Design Activity

”...design [is] the intentional creation of plans for a new kind of thing”. Parsons

SLIDE 21

Art of Programming Language Design Activity

”...design [is] the intentional creation of plans for a new kind of thing”. Parsons Choose one programming language Working in a group, investigate the following:

Key characteristics of the language design.

Historical context (how it started, when, by whom, the first language, etc.).

The purpose/usage (why is it there).
