Graphics program to sort lines

[lifeisgreat20009]

I want to make a "GRAPHICS PROGRAM" in C language that shows sorting of lines. Something like this:-

------------
-------------------

------

------------------------------------

after sorting the lines should appear as follows on the screen :-

-------
-----------------
---------------------
--------------------------------------

NOTE :- The lines are to be drawn using line() function. also the lines are to be sorted using quick sort algorithm.

Any help would be greatly appreciated.
Thanks !!!!!


I have tried it but it fails to work . The code is below !!!!!!

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
 
int main(void)
{
   /* request auto detection */
   int gdriver = DETECT, gmode, errorcode;
 
   int x1=50,y1=50,x2=100,y2=50,x3=70,y3=70,x4=150,y4=70;
   int x5=30,y5=90,x6=50,y6=90,i,l[3],temp,midx,midy;
 
 
 
   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "");
 
   /* read result of initialization */
   errorcode = graphresult();
   /* an error occurred */
   if (errorcode != grOk)
   {
      printf("Graphics error: %s\n", grapherrormsg(errorcode));
      printf("Press any key to halt:");
      getch();
      exit(1);
   }
   midx=getmaxx()/2;
   midy=getmaxy()/2;
   outtextxy(midx-50,10,"UNSORTED LINES");
   outtextxy(midx-50,midy-130,"SORTED LINES");
   line(0,0,getmaxx(),0);
    line(getmaxx(),0,getmaxx(),getmaxy());
    line(getmaxx(),getmaxy(),0,getmaxy());
    line(0,0,0,getmaxy());
 
   setcolor('5');
   line(x1,y1,x2,y2);
   line(x3,y3,x4,y4);
   line(x5,y5,x6,y6);
 
   l[0]=x2-x1;
   l[1]=x4-x3;
   l[2]=x6-x5;
   delay(1000);
   for(i=0;i<=2;i++)
   {
   if(l[i]>l[i+1])
   {
   temp=l[i];
   l[i]=l[i+1];
   l[i+1]=temp;
 
   }  }        delay(1000);
 
   line(x1,y1+110,l[0]+x1,y1+110); delay(1000);
   line(x1,y1+130,l[1]+x1,y1+130);   delay(1000);
   line(x1,y1+150,l[2]+x1,y1+150);
 
 
   getch();
   closegraph();
   return 0;
}

You could save yourself a lot of trouble by just looking at each integer and displaying dashes corresponding to the integer value.

That is, if it contains 5, you display - - - - - followed by a newline.
