The literature on programming languages contains an abundance of informal claims about their relative expressive power, but there is no framework for formalizing such statements nor for deriving interesting consequences. [52] This table provides two measures of expressiveness from two different sources.
In this context, the term script refers to a small program in such a language; typically, contained in a single file, and no larger than a few thousand lines of code. The scope of scripting languages ranges from small to large, and from highly domain-specific language to general-purpose programming languages. A language may start as small and ...
The variable declaration syntax of VB.NET is unusually difficult to precisely describe. Given that there exist the identifier suffixes ("modifiers"): type_character, available as an alternative to an As clause for some primitive data types; nullable_specifier; and; array_specifier; and that
Statement separator – demarcates the boundary between two statements; need needed for the last statement; Line continuation – escapes a newline to continue a statement on the next line; Some languages define a special character as a terminator while some, called line-oriented, rely on the newline.
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
Programming languages have been classified into several programming language generations. [1] Historically, this classification was used to indicate increasing power of programming styles. Later writers have somewhat redefined the meanings as distinctions previously seen as important became less significant to current practice.
The table shows a comparison of functional programming languages which compares various features and designs of different functional programming languages. Name
Below is a simple grammar, defined using the notation of regular expressions and Extended Backus–Naur form. It describes the syntax of S-expressions, a data syntax of the programming language Lisp, which defines productions for the syntactic categories expression, atom, number, symbol, and list:
