  2. Literal (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Literal_(computer_programming)

    In computer science, a literal is a textual representation (notation) of a value as it is written in source code. [1] [2] Almost all programming languages have notations for atomic values such as integers, floating-point numbers, and strings, and usually for Booleans and characters; some also have notations for elements of enumerated types and compound values such as arrays, records, and objects.

  3. String literal - Wikipedia

    en.wikipedia.org/wiki/String_literal

    A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the ...

    ^c Subranges are used to define the bounds of the array. ^d JavaScript's array are a special kind of object. ^e The DEPENDING ON clause in COBOL does not create a true variable length array and will always allocate the maximum size of the array.

  6. String (computer science) - Wikipedia

    A message like "file upload complete" is a string that software shows to end users. In the program's source code, this message would likely appear as a string literal. User-entered text, like "I got a new job today" as a status update on a social media service. Instead of a string literal, the software would likely store this string in a database.

  7. Constant (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Constant_(computer...

    One very basic way is by simply writing a literal number, character, or string into the program code, which is straightforward in C, C++, and similar languages. In assembly language, literal numbers and characters are done using the "immediate mode" instructions available on most microprocessors.

  8. Null character - Wikipedia

    en.wikipedia.org/wiki/Null_character

    The ability to represent a null character does not always mean the resulting string will be correctly interpreted, as many programs will consider the null to be the end of the string. Thus the ability to type it (in case of unchecked user input) creates a vulnerability known as null byte injection and can lead to security exploits. [10]

  9. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    The string is converted to a number value. JavaScript attempts to convert the string numeric literal to a Number type value. First, a mathematical value is derived from the string numeric literal. Next, this value is rounded to nearest Number type value. Boolean
