What is an expressive programming language?

In computer science, the expressive power (also called expressiveness or expressivity) of a language is the breadth of ideas that can be represented and communicated in that language. The more expressive a language is, the greater the variety and quantity of ideas it can be used to represent.

Which programming language is not a free form language?

Structured languages exist which are not free-form, such as ABC, Curry, Haskell, Python and others. Many of these use some variant of the off-side rule, in which indentation, rather than keywords or braces, is used to group blocks of code.

Is Python an expressive language?

Python is an expressive language. Expressive in this context means that a single line of Python code can do more than a single line of code in most other languages. The advantages of a more expressive language are obvious – the fewer lines of code you write, the faster you can complete the project.

Is Java an expressive language?

Java comes in with nearly identical expressiveness as C++ (both at 823 LOC/commit) but a vastly greater consistency (IQR of 277 vs 476).

Is JavaScript a free-form language?

This contrasts with dynamically-typed languages like JavaScript or PHP, where each variable can hold any type, and that type can change at runtime. A free-form language is one where there are no requirements about where various symbols have to go with regard to one another.

Why is C free-form language?

Wikipedia says that , In computer programming, a free-form language is a programming language in which the positioning of characters on the page in program text is insignificant. Program text does not need to be placed in specific columns as on old punched card systems, and frequently ends of lines are insignificant.

Is Java more expressive than C?

In contrast to assembly languages, C allows one to constrain variables to hold values from specific types, so it is more expressive here. In contrast to C, Java allows to test if a value is within the length a. length of an array a, so it is more expressive here.

Is Pascal a high-level language?

Pascal is a general-purpose, high-level language that was originally developed by Niklaus Wirth in the early 1970s. It was developed for teaching programming as a systematic discipline and to develop reliable and efficient programs.
