    Es bedeutet das du

    void drawball(int i,int j,int c1,int c2);

    nicht definiert hast 😮 ...

    du brauchst im Code etwas in der richtung:

    void drawball(int i,int j,int c1,int c2)
{
//...
}

    Aber mal ganz im Ernst... da hatte man auch selbst drauf kommen können... 😕

    Der Fehler ist ganz einfach, dass du die graphics.lib nicht miteingebunden hast.
