The ASCII code for double-quote is 34, and for single-quote is 39.

Then the character is inserted into the string at the appropriate places. Another solution is to construct the quote character from its character code, without having to write the quote character itself.adds quotation marks, etc.) in these languages, this can be used to circumvent the quoting problem. Some languages have a function for getting the 'source code representation' of a string (i.e.a backslash) in the string, which itself usually needs to be escaped, and so on.

However, including quotation marks in the string literal itself would be troublesome because it requires them to be escaped, which then necessitates the escaping character (e.g.

Part of the code usually needs to be stored as a string or structural literal in the language, which needs to be quoted somehow.

There are several difficulties that one runs into when writing a quine, mostly dealing with quoting: Empty programs producing no output are not allowed. The program should also contain some sort of self-reference, so constant expressions which return their own value which some top-level interpreter will print out. You are not allowed to read any external files with the source code. If the language allows it, you may add a variant that accesses the code directly. Write a program that outputs its own source code in this way. Often, the plain code and the quoted code have to be nested. The plain code then accesses the quoted code and prints it out twice, once unquoted and once with the proper quotation marks added. The usual way to code a quine works similarly to this paradox: The program consists of two identical parts, once as plain code and once quoted in some way (for example, as a character string, or a literal data structure). It can refer to the text-based program source.įor languages in which program source is represented as a data structure, 'source' may refer to the data structure: quines in these languages fall into two categories: programs which print a textual representation of themselves, or expressions which evaluate to a data structure which is equivalent to that expression. Who studied self-reference and quoting in natural language,Īs for example in the paradox ''Yields falsehood when preceded by its quotation' yields falsehood when preceded by its quotation.' It is named after the philosopher and logician
