#73. Quine



A quine is a computer program which takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs".

A quine is a fixed point of an execution environment, when the execution environment is viewed as a function transforming programs into their outputs. Quines are possible in any Turing-complete programming language, as a direct consequence of Kleene's recursion theorem. For amusement, programmers sometimes attempt to develop the shortest possible quine in any given programming language.

Your task is to write a program like this and it contains at least 10 visible characters.


自产生程序(英语:Quine),它以美国哲学家奎恩(Willard Van Orman Quine)命名,指的是输出结果为程序自身源码的程序。
