C/C++ program that prints its own source code as its output

Question

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);}
         


        

Answer 1

You can also define printf's prototype by hand.

const char *a="const char *a=%c%s%c;int printf(const char*,...);int main(){printf(a,34,a,34);}";int printf(const char*,...);int main(){printf(a,34,a,34);}
