Focus on issues: Linguistics of
Programming.
Two parts:
• Syntax (easy).
• Semantics (hard).
Programming (Language)
Paradigms
• FOUR PARADIGMS OF COMPUTING
• Imperative:
• WHAT DO WE DO NEXT ?
• Functional:
• WHAT IS THE FUNCTION’S VALUE ?
• Logic:
• WHAT CONDITIONS ARE NEEDED ?
• Object-Oriented:
• WHAT IS THE OBJECT’S BEHAVIOR ?
Topics Not Covered
• Programming Language Design.
• Programming Language
Implementation.
• Formal Models for Type Systems.
• Axiomatic Approach to Semantics.
• History of Programming Languages.

Some Observations
Programming Languages are:
• Like humans:
– Love/hate relationship.
• Incredibly diverse. PAL is listed among
the 2500+ languages at
http://people.ku.edu/~nkinners/
LangList/Extras/langlist.htm
• RPAL is also among 737 languages listed
at http://www.99-bottles-of-beer.net
Some Observations (cont’d)
Programming languages are:
• Subject to heated debates, (almost)
religious fervor.
– See comp.lang.* newsgroups.
• Constantly evolving, with many
dialects.
• Unpredictable when it comes to
achieving widespread use.
Some Observations (cont’d)
Programming languages are:
• Influential on programming practice
(and vice-versa).
– Goto’s, O-O programming.
• Influential on machine architecture
(and vice-versa). Think of:
– Stack support, parallel computing,
Internet.
– Lately, power efficiency.
Some Observations (cont’d)
Programming languages are:
• A lot of FUN !
