C++ Programming : Program 14-A

Program to draw 2 rectangles and fill 1 of them


 

#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.
