A string literal is the representation of a string value within the source code of a computer program. There are numerous alternate notations for specifying string literals, and the exact notation depends on the individual programming language in question. Nevertheless, there are some general guidelines that most modern programming languages follow.
Specifically, most string literals can be specified using:
- declarative notation;
- whitespace delimiters (indentation);
- bracketed delimiters (quoting);
- escape characters; or
- a combination of some or all of the above

Famous quotes containing the words string and/or literal:
“First you find a little thread, a little thread leads you to a string, and the string leads you to a rope. And from the rope you hang by the ... neck.”
—A.I. (Albert Isaac)
“Woe to the makers of literal translations, who by rendering every word weaken the meaning! It is indeed by so doing that we can say the letter kills and the spirit gives life.”
—Voltaire [François Marie Arouet] (1694–1778)
