Study Notes
CIS217: Concepts of Programming Languages - Chapter 1 - Preliminaries
-
Reasons for Studying Programming Languages:
- Increased ability to express ideas: Language's expressive power influences thought processes.
- Improved background for choosing appropriate languages: Understanding different languages allows for informed choices.
- Increased ability to learn new languages: Continuous evolution necessitates continuous learning in the field.
- Better understanding of significance of implementation: Understanding design choices improves language usage.
- Overall advancement of computing: Language choice has impacted the advancement of computing.
Programming Domains
-
Scientific applications: Large floating-point computations are required and tools like Fortran and ALGOL 60 were initially used.
-
Business applications: COBOL emerged to handle financial reporting, decimal arithmetic, and character data. PCs revolutionized business computing.
-
Artificial intelligence: Symbolic rather than numeric computations; linked lists are often used rather than arrays. Languages such as LISP, Prolog, and Scheme are utilized.
-
Systems programming: Requirements for continuous use require high efficiency, low level features, and ability to interface with external devices. Languages like 'C' are utilized due to speed and low-level access.
-
Web software: The World Wide Web uses a variety of languages: Markup languages (HTML), Scripting (PHP), and general purpose languages (Java). JavaScript is client-side, interpreted by browsers. PHP is server-side, interpreted on the server before being sent to the client browser.
Language Evaluation Criteria
-
Readability: Ease with which programs can be read and understood
-
Writability: Ease with which a language can be used to create programs
-
Reliability: Conformance to specifications, performs as intended
-
Cost: Total cost of developing, testing, and maintaining a program
-
Portability: Ease of moving programs between implementations
-
Generality: Applicability to a wide range of applications
-
Well-defined: Completeness and precision of the language's official document
Influences on Language Design
-
Computer Architecture: The von Neumann architecture has significantly impacted programming languages. Instruction fetch-execute cycle are fundamental to how CPU's run programs.
-
Programming Methodologies:
- Initial focus on machine efficiency
- Shift to people efficiency (readability, better control structures), structuring, top-down design, step-wise refinement
- Transition from process oriented to data oriented programming (data abstraction)
- Introduction of object-oriented programming (data abstraction, inheritance, polymorphism).
Language Categories
-
Imperative: Uses variables, assignments, and iteration to express computation. Examples include C, Java, JavaScript, Visual BASIC .NET, C++.
-
Functional: Computation via applying functions to parameters. Examples include LISP, Scheme, ML, and F#.
-
Logic: Rule-based programming; rules are not specified in a particular order. Example is Prolog.
-
Markup/Programming Hybrid: Markup languages extended to support programming. Examples include JSTL and XSLT.
Language Design Trade-offs
-
Reliability vs. Cost of execution: Balancing reliable execution with the performance cost of reliability checks (e.g., error handling, safety measures).
-
Readability vs. Writability: Balancing the ease of understanding code with the ability to write compact, efficient code.
Implementation Methods
-
Compilation: Translates high-level code to machine code; is faster at execution but slower during translation. Examples include compilers for C, COBOL, C++, and Ada.
-
Pure Interpretation: Programs are interpreted by another program; easier debugging in source code, but slower execution. Examples include interpreters for JavaScript and PHP.
-
Hybrid Implementation: Combines aspects of compilation and interpretation; often uses intermediate representation and interpreters or translators. Example is Java bytecode. The JVM is a virtual machine that interprets.
Programming Environments
- Tools for Software Development: Collections of tools for creating programming projects. Examples include UNIX, Borland JBuilder, Microsoft Visual Studio .NET, and NetBeans.
Summary
- Programming language study is important for understanding diverse program constructs and choosing suitable languages for projects.
- Key criteria for evaluating languages include readability, writability, reliability, and cost.
- Core implementation methods are compilation, pure interpretation, and hybrid implementation.
- Programming environments encompass tools and platforms for software development (e.g., UNIX, IDEs like Visual Studio).
