Last Updated :

The header file graphics.h contains setfillstyle() function which sets the current fill pattern and fill color. floodfill() function is used to fill an enclosed area. Current fill pattern and fill color is used to fill the area.
Syntax :
void setfillstyle(int pattern, int color)
void floodfill(int x, int y, int border_color)
Examples :
Input : pattern = HATCH_FILL, Color = RED
circle : x = 250, y = 250, radius = 100
floodfill : x = 250, y = 250, border color =15
Output :
Input : pattern = LTSLASH_FILL, Color = RED
rectangle : left = 200, top = 200, right = 450, bottom = 450
floodfill : x = 201, y = 201, border_color = 15
Output :
Below is the table showing INT VALUES corresponding to Colors :

#include <graphics.h>
int main()
{
int gd = DETECT, gm;
initgraph(&gd, &gm, " ");
int x_circle = 250;
int y_circle = 250;
int radius=100;
int border_color = WHITE;
setfillstyle(HATCH_FILL,RED);
circle(x_circle,y_circle,radius);
floodfill(x_circle,y_circle,border_color);
getch();
closegraph();
return 0;
}
