All logical operators exist in C and C++ and can be overloaded in C++, albeit the overloading of the logical AND and logical OR is discouraged, because as overloaded operators they behave as ordinary function calls, which means that both of their operands are evaluated, so they lose their well-used and expected short-circuit evaluation property ...
The asterisk (/ ˈ æ s t ər ɪ s k / *), from Late Latin asteriscus, from Ancient Greek ἀστερίσκος, asteriskos, "little star", [1] [2] is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star.
The ampersand can be used to indicate that the "and" in a listed item is a part of the item's name and not a separator (e.g. "Rock, pop, rhythm & blues and hip hop"). [citation needed] The ampersand may still be used as an abbreviation for "and" in informal writing regardless of how "and" is used.
ABAP supports two different kinds of comments. If the first character of a line, including indentation, is an asterisk (*) the whole line is considered as a comment, while a single double quote (") begins an in-line comment which acts until the end of the line.
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.
The bitwise AND operator is a single ampersand: &. It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form.
Generally, an escape character is not a particular case of (device) control characters, nor vice versa.If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one.
The + sign is a simplification of the Latin: et (comparable to the evolution of the ampersand &). [7] The − may be derived from a macron ̄ written over m when used to indicate subtraction; or it may come from a shorthand version of the letter m itself.
