Uppercase Lowercase

Uppercase and lowercase are two writing styles used to differentiate between characters in text. Uppercase (or capital letters) is the larger letters and lowercase is the smaller letters.

Converting between uppercase and lowercase, also called case switching, consists in transforming the characters of a text into either uppercase or lowercase.

On dCode, the software analyses if text characters (Unicode characters are taken into account) are upper case or lower case and realize the desired transformations.

In computing, case is the name given to the distinction between uppercase and lowercase characters. Case changing is the term for switching from one case to the other. Also when searching for text, the case can be ignored (a word written in upper or lower case will be treated indifferently).

Case is used to add structure and clarity to text. It makes it possible to distinguish between proper nouns, titles, acronyms and the beginnings of sentences.

Also, case can convey semantic information, such as in programming where case can indicate variables, functions, or constants.

A steganography technique uses upper and lower case letters to hide and encode information in 0 and 1.

Bacon cipher or more generally any binary format can use this method.

CamelCase is a writing convention where words are glued together and each word, except the first, begins with a capital letter.

It is often used to name variables or functions in programming.

A variation is the PascalCase where the first letter (initial) is uppercase (uppercase).
