a prof showed me this code, its kind of neat...
take a guess at what the output of this code is before you compile and run it, its interesting. post your guess first then see how close you were!!
Code:main(){char*a="main(){char*a=%c%s%c;print(a,34,a,34,10);}%c";printf(a,34,a,34,10);}
displays main(){char*a=%c%s%c;print(a,34,a,34,10);}%c";prin tf(a,34,a,34,10);}
Actually, it displays:Originally posted by revelation437

hmm, pretty cool stuff. i didnt know they were called 'quines'Originally posted by Salem

Quines are just programs that print out their own source code. You can even have a "Null Quine."
Null Quine-
Code:
actually it wont print anything
C:\blah.cpp(7) : error C2065: 'print' : undeclared identifier
guns dont kill people, abortion clinics kill people.
hmmm. thats weird, works for me.Originally posted by dP munky

Yeah, I guess some know to look into stdio.h by itself, and others you need to make sure you include the header. You do in MSVC++, I know that much. I think in Dev-C++, you don't, but I'm not sure...Originally posted by Munkey01

actually the quine posted has a typo, it should be:
main(){char*a="main(){char*a=%c%s%c;printf(a,34,a, 34,10);}%c";printf(a,34,a,34,10);}
the other important thing is that this is C, not C++, be sure to name your test file "quine.c". You will get some warnings, but it should compile.
Here's a quine that is also a palindrome:
Code:/**/char q='"',*a="*//**/char q='%c',*a=%c%s%c*/};)b(stup;]d[b=]d-852 [b)--d(elihw;)q,a,q,q,2+a,b(ftnirps{)(niam;031=d tni;]952[b,",b[259]; int d=130;main(){sprintf(b,a+2,q,q,a,q);while(d--)b[258-d]=b[d];puts( b);}/*c%s%c%=a*,'c%'=q rahc/**//*"=a*,'"'=q rahc/**/

None of those should even compile. It is not valid in C++ to declare main without a returntype.
