שלום, אני מתחיל בC++ ויש לי את התוכנה DEV C++
אז יש לי כמה בקשות ובבקשה תענו על כולם

1)איך עושים שהקוד של הכדור שיוכל לזוז דרך החיצים (קוד למטה)
2)אפשר דוגמא של משחק שיצרתם (כולל קוד)

הקוד של הכדור:

בתור מישהו שמתחיל C++ התחלת רחוק מידי מנקודת ההתחלה.

קודם תלמד מה זה C++ ואיך מתכנתים בעזרתה דברים פשוטים ואז תעבור לדברים מסובכים יותר.
