Program to draw 2 rectangles and fill 1 of them in cpp

#include <iostream.h>
#include <conio.h>
#include <graphics.h>
#include <ctype.h>
#include <stdlib.h>
#include <stdio.h>
void main()
{
clrscr();
int gd = DETECT,gm,errorcode; //Requesting auto-detection.
//Initializing graphics and local variables.
initgraph (&gd, &gm, “d:\bc3\bgi”); //Path where graphics drivers are installed
//Read result of initialization.
errorcode = graphresult();
//An error occured.
if (errorcode != grOk)
{
cout << “Graphics error occured : \n” << grapherrormsg(errorcode) << endl;
cout << “Press any key to stop : “;
getch();
exit(1);
}/*Drawing a rectangle having top LHS vertex at (300, 300)
and bottom RHS vertex at (600, 400)*/
rectangle(300, 300, 600, 400);
rectangle(100, 100, 200, 200);
getch();
floodfill(120, 120, WHITE);
getch();
closegraph();
}

This graphics program draws two rectangles, but fills in only one of them with a white
color using the ‘floodfill’ command.
