Study Notes
Introduction to Programming Languages
- Programming languages are used to communicate with computers.
- Operating systems are software collections that control computer functions.
- Programming languages have rules (syntax) for word usage and punctuation.
- Mistakes in syntax are called syntax errors.
- Programs are written in a programming language and stored in memory.
- Source code needs translation to machine language to be executed.
- Source code is translated into object code, which is machine language.
- Binary language (machine language) is represented as a series of 0s and 1s.
- Programming language components are checked by compilers or interpreters for errors.
Reasons for Studying Programming Concepts
- Increased capacity to express ideas.
- Improved background for choosing appropriate languages.
- Increased ability to learn new languages.
- Better understanding of the significance of implementation.
- Better use of languages already known.
- Overall advancement of computing.
Programming Domains
- Scientific applications
- Business applications
- Artificial intelligence
- Web software
Language Evaluation Criteria
- Criteria used to evaluate programming languages.
- Readability
- Writability
- Reliability
- Cost (training, writing, compiling, execution, implementation, and reliability)
Readability
- Simplicity is key to readability.
- Languages with fewer constructs are easier to learn than those with many.
- Feature multiplicity (multiple ways to do the same thing) also decreases readability.
Writability
- Writability measures how easily a language is used to create programs.
Expressivity
- Expressivity refers to the power of operators in a language to accomplish complex computations efficiently.
- Convenient ways to express computations, such as count++ in C, improve expressivity.
Reliability
- Reliability means performing tasks as specified under all conditions.
- Type checking (detecting errors at compile or runtime) and exception handling (catching errors) are essential for reliability.
- Aliasing (using multiple names to refer to the same memory cell) can reduce reliability if not handled carefully.
Cost
- Cost includes training, program writing, compiling, executing, implementing, and maintaining.
- Simplicity and orthogonality reduce these costs.
Types of Programming Languages
- Machine language is the language understood by the computer hardware itself.
- Assembly languages use symbolic codes and require translation (assembly) into machine code.
- High-level languages are easier for humans to read and write but need translation. Examples include Basic, Fortran, Cobol, Pascal, C, and C++.
