    goto www.google.com

    type in
    polygon fill algorithm

    Start reading
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Using Win32 primitive drawing, you could use this function:

    BOOL Polygon(HDC, hDC, CONST POINT* pt, int iCount);

    All you have to do, is to fill an array with points.. and it will connect them for you.

    Code:
    void GamePaint(HDC hDC)
    {
         POINT points[3];
         points[0] = { 5, 10};
         points[1] = {25, 30};
         points[2] = {15, 20};
         Polygon(hDC, points, 3);
    }
