C/C++ program that prints its own source code as its output
c, quine
Solution
The trick here is that most compilers will compile without requiring you to include `stdio.h`.
They will usually just throw a warning.
Problem
Wikipedia says it's called a quine and someone gave the code below: ``` char*s="char*s=%c%s%c;main(){printf(s,34,s,34);}";main(){printf(s,34,s,34);} ``` But, obviously you have to add ``` #include <stdio.h> //corrected from #include <stdlib.h> ``` so that the `printf()` could work. Literally, since the above program did not print `#include <stdio.h>`, it is not a solution (?) I am confused about the literal requirement of "print its own source code", and any purpose of this kind of problems, especially at interviews.
