neet to explain how this output is coming

[amarg]

Hi All,

I got one crap code.

code is

main(a){printf(a,34,a="main(a){printf(a,34,a=%c%s%c,34);}",34);}

and output is

main(a){printf(a,34,a="main(a){printf(a,34,a=%c%s%c,34);}",34);}

I don't know how this output is coming from the code.
Please help me to find out the explanation.

Regards,
Amar

There are a number of issues with this code. Is it a homework assignment? If not, can you elaborate on what this code is intended to accomplish? Thanks in advance.

The code is an example of a quine, a program whose output is its own source code. The poster is only asking how it does that, not what's wrong with it.

The variable

a

is never declared, so it is treated an an int. The assignment

a="main(a){printf(a,34,a=%c%s%c,34);}"

luckily appears to be occurring before

a

is evaluated as the first argument to

printf

. Since the value of that literal is just a char*, it can be assigned to an int. Not the most correct thing, but it works. The rest is just printf stuff. If you can't figure that out, ask again.

There's gotta be an &quot;#include <stdio.h>&quot; in there, right?
