حيث يتم كسر الحلقة عند القيمة 3 و لا يتم عرض باقي الحلقة ..

مثال متقدم يشمل array , loop , if , break..

تستخدم الدالة لكسر عملية البحث عن رقم في مصفوفة arrayOfInts ..
يعني اذا وجدت الرقم 12 اخرج من الحلقتين ..

حيث تم تجاهل العدد 5 من الحلقة و تم اكمال الحقة بشكل طبيعي ..

مثال متقدم

كود :

[/COLOR][/COLOR]

يقوم هذا الكود بالبحث عن الحرفين P , S في متغير نصي و هو SearchMe ..

ثالثا : الحالة Return ..
و تستخدم في حالتين اما ارجاع قيمة لدالة او عدم ارجاع اي قيمة ...

كود :
