help me with this c graphics program

[arun.m]

hello

i have got a c graphics program of a demonstration of a flying kite.i have to alter this program to make a user input of the rope of kite.For example when when the program start it will be asking for a user input length of the rope of the kite.so that we can adjust the height of the kite...please kindly help...

this is the original program can you please alter this with my requirement

my requirement is to set a user input for the height of the kite while flying

Note:i am a new to the c language.i ma doing this for my friend.

#include<stdio.h>
#include<graphics.h>
#include<alloc.h>
int main(void)
{
void *kite;
int s,x,y,gd=DETECT,gm,r;
initgraph(&gd,&gm,"c:\tc");
setcolor(10);
moveto(100,100);
lineto(125,75);
lineto(150,100);
lineto(120,130);
lineto(130,130);
lineto(125,125);
lineto(100,100);  //this completes the outline design of kite
setfillstyle(SOLID_FILL,BLUE);
floodfill(125,100,10);
floodfill(125,127,10);
arc(125,120,40,140,31);
line(125,125,125,75);
line(125,110,150,130);
line(125,94,150,130);

s=imagesize(100,75,150,130);
kite=(void*)malloc(s);

getimage(100,75,150,130,kite);
putimage(100,75,kite,XOR_PUT);
x=100,y=75;

while(!kbhit())
{
setcolor(10);
putimage(x,y,kite,XOR_PUT);
setcolor(YELLOW);
line(x+50,y+55,639,479);
delay(100);
putimage(x,y,kite,XOR_PUT);
setcolor(0);
line(x+50,y+55,639,479);

r=rand();

switch(r%4)
{
case 0:x=x+10; break;
case 1:x=x-10; break;
case 2:y=y+10; break;
case 3:y=y-10;break;
}
if(x>640) x-=40;
if(x<40) x+=40;
if(y>479) y-=40;
if(y<40) y+=40;
}
getch();
closegraph();
return 0;
}

Nice homework. Too bad that's against forum rule 2.c
