level-number type OCCURS min-size TO max-size «TIMES» DEPENDING «ON» size. [e] ^a In most expressions (except the sizeof and & operators), values of array types in C are automatically converted to a pointer of its first argument.
This is an accepted version of this page This is the latest accepted revision, reviewed on 5 January 2025. Language for communicating instructions to a machine The source code for a computer program in C. The gray lines are comments that explain the program to humans. When compiled and run, it will give the output "Hello, world!". A programming language is a system of notation for writing ...
The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.
With respect to a language definition, the syntax of Comments can be classified many ways, including: Line vs. block – a line comment starts with a delimiter and continues to the end of the line ( newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines
A language can have different equivalent grammars, such as equivalent regular expressions (at the lexical levels), or different phrase rules which generate the same language. Using a broader category of grammars, such as LR grammars, can allow shorter or simpler grammars compared with more restricted categories, such as LL grammar, which may ...
This is an index to notable programming languages, in current or historical use. Dialects of BASIC, esoteric programming languages, and markup languages are not included. A programming language does not need to be imperative or Turing-complete, but must be executable and so does not include markup languages such as HTML or XML, but does include domain-specific languages such as SQL and its ...
different levels of input datatypes, as in container types and generic programming. Each of these programming styles has contributed to the synthesis of different programming languages. [40] A programming language is a set of keywords, symbols, identifiers, and rules by which programmers can communicate instructions to the computer. [41]
Reflective programming languages let programs examine and possibly modify their high-level structure at runtime or compile-time. This is most common in high-level virtual machine programming languages like Smalltalk, and less common in lower-level programming languages like C. Languages and platforms supporting reflection:
