Some other programming languages have varying case sensitivity; in PHP, for example, variable names are case-sensitive but function names are not case-sensitive. This means that if a function is defined in lowercase, it can be called in uppercase, but if a variable is defined in lowercase, it cannot be referred to in uppercase.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
C doesn't have a function to uppercase a whole string. toupper() takes and returns an integer as its arguments, NOT strings. It's prototype: int toupper(int c); If c is a lowercase letter (a-z), topupper() returns the uppercase version (A-Z). Otherwise toupper() returns c unchanged. toupper() does not convert international characters (those ...
Small caps, petite caps and italic used for emphasis True small caps (top), compared with scaled small caps (bottom), generated by OpenOffice.org Writer. In typography, small caps (short for small capitals) are characters typeset with glyphs that resemble uppercase letters but reduced in height and weight close to the surrounding lowercase letters or text figures.

Locally scoped variables and subroutine names are lowercase with infix underscores. Subroutines and variables meant to be treated as private are prefixed with an underscore. Package variables are title cased. Declared constants are all caps. Package names are camel case excepting pragmata—e.g., strict and mro—which are lowercase. [36] [37]
The x must be lowercase in XML documents. The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text.
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).
Like raw strings, there can be any number of equals signs between the square brackets, provided both the opening and closing tags have a matching number of equals signs; this allows nesting as long as nested block comments/raw strings use a different number of equals signs than their enclosing comment: --[[comment --[=[ nested comment ...
