In C and C++, keywords and standard library identifiers are mostly lowercase. In the C standard library, abbreviated names are the most common (e.g. isalnum for a function testing whether a character is alphanumeric), while the C++ standard library often uses an underscore as a word separator (e.g. out_of_range).
Snake case (sometimes stylized autologically as snake_case) is the naming convention in which each space is replaced with an underscore (_) character, and words are written in lowercase. It is a commonly used naming convention in computing, for example for variable and subroutine names, and for filenames.
This is an alphabetical list of television program articles (or sections within articles about television programs). Spaces and special characters are ignored. This list covers television programs whose first letter (excluding "the") of the title are Q and R.
converts the operand to lowercase toupper: towupper: converts the operand to uppercase — iswctype: checks whether the operand falls into specific class — towctrans: converts the operand using a specific mapping — wctype: returns a wide character class to be used with iswctype — wctrans: returns a transformation mapping to be used with ...
There is rarely anything to say about file extensions; instead, these should in almost all cases be redirects to an article about the file format, a list of file formats (e.g. for the many text-like formats) or a program using the file format (the sole or most common program, e.g. ".doc" → Microsoft Word).
Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2 O" (with subscript markup). In reality, many fonts that include these characters ignore the Unicode definition, and instead design the digits for mathematical numerator and denominator glyphs, [3] [4] which are aligned with the cap line and the baseline, respectively.
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 lowercase "a" and uppercase "A" are the two case variants of the first letter in the English alphabet. In computers, case sensitivity defines whether uppercase and lowercase letters are treated as distinct (case-sensitive) or equivalent (case-insensitive).
