Some naming conventions limit whether letters may appear in uppercase or lowercase. Other conventions do not restrict letter case, but attach a well-defined interpretation based on letter case. Some naming conventions specify whether alphabetic, numeric, or alphanumeric characters may be used, and if so, in what sequence.
Camel case is named after the "hump" of its protruding capital letter, similar to the hump of common camels.. Camel case (sometimes stylized autologically as camelCase or CamelCase, also known as camel caps or more formally as medial capitals) is the practice of writing phrases without spaces or punctuation and with capitalized words.
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 .
In Ruby a variable is automatically considered immutable if its identifier starts with a capital letter. In Go, the capitalization of the first letter of a variable's name determines its visibility (uppercase for public, lowercase for private). In some languages such as Go, identifiers uniqueness is based on their spelling and their visibility. [2]
Converts the first ASCII letter character of a string to uppercase. This behavior is different from the magic word ucfirst, which affects the first character of a string regardless of whether it is a letter or not.
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).
The lower-case "a" and upper-case "A" are the two case variants of the first letter in the English alphabet.. Letter case is the distinction between the letters that are in larger uppercase or capitals (more formally majuscule) and smaller lowercase (more formally minuscule) in the written representation of certain languages.
Using uppercase for keywords remains in use as a convention for writing grammars for lexing and parsing – tokenizing the reserved word if as the token class IF, and then representing an if-then-else clause by the phrase IF Expression THEN Statement ELSE Statement where uppercase terms are keywords and capitalized terms are nonterminal symbols ...
