Study Notes

Reasons to Study Programming Languages

Study of programming languages helps in increasing the capacity to express programming concepts, which is influenced by the expressive power of the language.
The tools used to express ideas have a profound influence on our thinking habits and abilities, as stated by Dijkstra.
Learning new languages can increase the range of software development thought process by simulating new constructs.

Improved Background for Choosing Appropriate Languages

Study of programming languages helps in choosing the right language for a given task, as different languages are more suitable for specific tasks.
Abraham Maslow's quote "To the man who only has a hammer in the toolkit, every problem looks like a nail" illustrates the importance of having multiple languages in one's toolkit.

Increased Ability to Learn New Languages

Study of different programming languages helps in learning new languages by learning syntax and semantics of different languages and understanding different design methodologies.

Understanding the Significance of Implementation

Understanding implementation issues leads to an understanding of why languages are designed the way they are, and ultimately leads to efficient use of the language.
Examples of implementation issues include Row vs. column major in FORTRAN and recursion, which can affect the efficiency of programs.

Increased Ability to Design New Languages

Learning a number of programming languages helps in understanding the pros and cons of different language features and issues related to these features.
This knowledge can help in designing a new language for any purpose.

Language Evaluation Criterion

Capers Jones' Programming Languages Table relates languages with productivity, showing that higher-level languages yield more productivity than lower-level languages.
The table shows the average productivity per staff month for different language levels, ranging from 5 to 100 Function Points.
Examples of languages with their corresponding levels are Assembly (1), C (2.5), Pascal (3.5), LISP (5), BASIC (5), C++ (6).
