For a sorted dictionary, the programmer could choose to use a SortedDictionary<TKey, TValue> or use the .Sort LINQ extension method when enumerating. The following demonstrates enumeration using a foreach loop :
This is a comparison of English dictionaries, which are dictionaries about the language of English.The dictionaries listed here are categorized into "full-size" dictionaries (which extensively cover the language, and are targeted to native speakers), "collegiate" (which are smaller, and often contain other biographical or geographical information useful to college students), and "learner's ...
In the most SQL dialects the double dash (--) can be used instead. Esoteric languages. Many esoteric programming languages follow the convention that any text not executed by the instruction pointer (e.g., Befunge) or otherwise assigned a meaning (e.g., Brainfuck), is considered a "comment".
It is usually used to deconstruct algebraic data types. ^c In languages of the Pascal family, the semicolon is not part of the statement. It is a separator between statements, not a terminator. ^d END-IF may be used instead of the period at the end.
Like natural languages, programming languages follow rules for syntax and semantics. There are thousands of programming languages [1] and new ones are created every year. Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career.
It has a relatively uncluttered visual layout and uses English keywords frequently where other languages use punctuation. Python aims to be simple and consistent in the design of its syntax, encapsulated in the mantra "There should be one— and preferably only one —obvious way to do it", from the Zen of Python. [2]
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 ...
The syntax of most programming languages uses English keywords, and therefore it could be argued some knowledge of English is required in order to use them. Some studies have shown that programmers nonnative to English self-report that English is their biggest obstacle to programming proficiency. [ 13 ]
