Answer 1

Answer:

#include<stdio.h>

#include<graphics.h>

#include<math.h>

int main()

{

int gd,gm;

int r,i,a,b,x,y;

float PI=3.14;

 

detectgraph(&gd,&gm);

initgraph(&gd,&gm,"C:\\TURBOC3\\BGI");

 

//draw the top rectangle and color it

setcolor(RED);

rectangle(100,100,450,150);

setfillstyle(SOLID_FILL,RED);

floodfill(101,101,RED);

//draw the middle rectangle and color it

setcolor(WHITE);

rectangle(100,150,450,200);

setfillstyle(SOLID_FILL,WHITE);

floodfill(101,151,WHITE);

//draw the bottom rectangle and color it

setcolor(GREEN);

rectangle(100,200,450,250);

setfillstyle(SOLID_FILL,GREEN);

floodfill(101,201,GREEN);

//draw the circle

a=275; //center

b=175; //center

r=25; //radius

setcolor(BLUE);

circle(a,b,r);

//spokes

for(i=0;i<=360;i=i+15)

{

 x=r*cos(i*PI/180);

 y=r*sin(i*PI/180);

 line(a,b,a+x,b-y);

}

getch();

closegraph();

return 0;

}
