Where am I going wrong?

Ok so I am using the dev-C++ compiler not M$ so I'm not sure what headers I need to have this project compile without errors. Can anyone tell me what I need to change to make this work?
Thanks in advance.

#include <iostream.h>
#include <stdlib.h>
#include <stdio.h>
#include <graph.h>
int main()
{
int x,y,color,index;

_setvideomode(_vres16color);

for (index = 0; index<10000; index++)
{

x = rand()%640;
y = rand()%480;
color = rand()%16;
_setcolor(color);
_setpixel(x,y);

}

while(!kbhit()){}

_setvideomode(_defaultmode);

}

Ok I think the problem is in the header <graph.h> but I try graphics.h and it doesn't work, I'm lost where can I find out what headers I need to plot points?

Hey! I've never used that complier. I've allways worked with Turbo C++. Anyway, the library is called graphics.h, as you said correctly. The problem is that _setvideomode, setpixel and _setcolor functions do not exist in graphics.h

setcolor is defined allright.
setpixel (doesn't exist) --> use getpixel and putpixel
setvideomode --> must before determin the graphics card values, etc (search in help)

Hope It works for you!
