Hali!

Kellemes feladatokat kaptok, nekem is jó, mert "retrózhatok".
Nos, több megoldása is lehet a feladatnak, Én az alábbi módszert választottam, elsősorban mert x64 Vista alatt ne futnak a DOS-os c/cpp editorok, ebből adódóan a kurzorpozicíóval, assembly betéttel, megszakításokkal nem tudok mit kezdeni.(ugyanis úgy is meg lehetett volna oldani, hogy egyből megjelenik a tábla, és egyből megjelenik rajt a bevitt mezőn az "érme"....)

Lesz bent egy teljesen kikommentezett rész, azt csak azért hagytam bent, hogy még egy mátrix definíciót is láss. Sajna ott viszont már "keményen" mútatókkal lehet volna csak operálni, és ha valaki nincs tisztában velük, akkor tényleg nem fog érteni belőle semmit....

UI: remélem jól értelmeztem a feladatot...
