Flying Kite

Program to implement a FLYING KITE using built-in functions available in the library.

void main() 
{ 
    int gd=DETECT,gm; 
    int color; 
    int x=10,y=1,inc_x=10,inc_y=10;
    int poly[10];

    initgraph(&gd,&gm," ");

    while(!kbhit())
    {
 x += inc_x;
 if(x > 200)
  inc_x = -5;
 if(x < 0 )

 if(y < 0 )
  inc_y = 10;
 cleardevice();
 setcolor(WHITE);

 setfillstyle(SOLID_FILL,RED);
 fillpoly(5,poly);

 setlinestyle(SOLID_LINE,1,3);

Hope, it helped! :)
