Draw animation circles using C++ GUI Graphics

Here you will learn how to draw animation circles using C++ GUI Graphics Library .

Write a Program to draw animation using increasing circles filled with different colors and patterns.

#include<graphics.h>  
#include<conio.h>  
void main()  
{  
    intgd=DETECT, gm, i, x, y;  
    initgraph(&gd, &gm, "C:\\TC\\BGI");  
    x=getmaxx()/3;  
    y=getmaxx()/3;  
    setbkcolor(WHITE);  
    setcolor(BLUE);  
    for(i=1;i<=8;i++)  
          {  
        setfillstyle(i,i);  
        delay(20);  
        circle(x, y, i*20);  
        floodfill(x-2+i*20,y,BLUE);  
    }  
    getch();  
    closegraph();  
}  

OUTPUT

Program to make screen saver in that display different size circles filled with different colors and at random places.

#include<stdio.h>  
#include<conio.h>  
#include"graphics.h"  
#include"stdlib.h"  
void main()  
{  
    intgd=DETECT,gm,i=0,x,xx,y,yy,r;  
    //Initializes the graphics system  
    initgraph(&gd,&gm,"c:\\tc\\bgi");  
    x=getmaxx();  
    y=getmaxy();  
    while(!kbhit())  
    {  
        i++;  
      //    setfillstyle(random(i),random(30));  
  
        circle(xx=random(x),yy=random(y),random(30));  
        setfillstyle(random(i),random(30));  
        floodfill(xx,yy,getmaxcolor());  
        delay(200);  
    }  
    getch();  
}
