Answer 2

敲出来是一个我爱你的图形。

for(double y=2.5;y>=-1.6;y=y-0.2)
{
for(double x=-3;x<=4.8;x=x+0.1)
((x*x+y*y-1)*(x*x+y*y-1)*(x*x+y*y-1)<=3.6*x*x*y*y*y
|| (x>-2.4 && x<-2.1 && y<1.5 && y>-1)
|| (((x<2.5 && x>2.2) || (x>3.4 && x<3.7)) && y>-1 && y<1.5)
|| (y>-1 && y<-0.6 && x<3.7 && x>2.2))?printf("*"):printf(" ");
printf("\n");
}
