Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases.
Support for trigraphs in C++ was removed in C++17, and support for them in C is planned to be removed in C23. In Visual Basic (and some other BASIC dialects) the backslash is used as an operator symbol to indicate integer division. [11] This rounds toward zero. The ALGOL 68 programming language uses the "\" as its Decimal Exponent Symbol.
By extension, ++ is sometimes used in computing terminology to signify an improvement, as in the name of the language C++. In regular expressions, + is often used to indicate "1 or more" in a pattern to be matched. For example, x+ means "one or more of the letter x". This is the Kleene plus notation.
A whitespace character is a character data element that represents white space when text is rendered for display by a computer.. For example, a space character (U+0020 SPACE, ASCII 32) represents blank space such as a word divider in a Western script.
(The term "exception" as used in IEEE 754 is a general term meaning an exceptional condition, which is not necessarily an error, and is a different usage to that typically defined in programming languages such as a C++ or Java, in which an "exception" is an alternative flow of control, closer to what is termed a "trap" in IEEE 754 terminology.)
The C++ Core Guidelines [91] are an initiative led by Bjarne Stroustrup, the inventor of C++, and Herb Sutter, the convener and chair of the C++ ISO Working Group, to help programmers write 'Modern C++' by using best practices for the language standards C++11 and newer, and to help developers of compilers and static checking tools to create ...
The C++ programming language (originally named "C with Classes") was devised by Bjarne Stroustrup as an approach to providing object-oriented functionality with a C-like syntax. [65] C++ adds greater typing strength, scoping, and other tools useful in object-oriented programming, and permits generic programming via templates.
The zero-width space ( ), abbreviated ZWSP, is a non-printing character used in computerized typesetting to indicate where the word boundaries are, without actually displaying a visible space in the rendered text.
