quine
This was one of my favorite piece of code when I first learned C programming language. This is known as "Quine". Basically program gives its source code as its output.
Please look at the websites below that I found online about "Quine".

To compile:
$ make
To run the binary:
$ ./quine
To check the difference between the source code and the output of the code:
$ make check
To remove the binary files:
$ make clean
If you don't have make you can compile 'quine.c' with gcc directly:
$ gcc -Wall quine.c -o quine
Let's play... We can compile the output of the code as well:
$ ./quine > output_source.c
$ gcc -Wall output_source.c -o output_source
$ ./output_source
