void K(int X1,int Y1, int X2, int Y2,char C){
int i;

for(i=X1;i<X2;i++){V(i,Y1,Y2,C);}
}
you should swap (x1 and x2) and( y1 and y2) here

Yes!! That certainly was a bad mistake... thank you for that! :D

i found another problem in your code
i think this function

bcoz if new and old color be same , your fill function check a cell over and over
you can use a map or a 2-D array for marking cells that you visited already
and
maybe x1 is greater than x2 or y1 > y2 , you should swap them

I think I already do those things...


void V(int X, int Y1, int ...
