 void main()

	clrscr();

Error:
Compiling screensaver.cpp:
Error screensaver.cpp 13:Function 'graph' should have prototype


help me!

redundant #include<iostream.h>

put graph()'s definition (or prototype) above the main() function

[FShapouran]

It does not show anything, and quickly returns to IDE

Do you perhaps mean initgraph()?

[FShapouran]

Error screensaver.cpp 13:too few paremeters in call to 'initgraph(int far*,int far*,const far*)'

[Duthomhas]

Are you even bothering to look at the documentation for this stuff?
How do you know functions like fillellipse() exist if you don't have some kind of reference?

I tried this on another computer and it worked in windows xp
