#define q(k)main(){return!puts(#k"\nq("#k")");}
q(#define q(k)main(){return!puts(#k"\nq("#k")");})
This code can print itself on the screen,however,I have a difficulty in reading it,especially that two #K,how does it work?I know how #define q(k) 2*k works,but I really have no idea about this code.Please help me to analyse it!thank you!
