مقدار دهی تابع پویا با استفاده از کلاس ( رفع اشکل + کمک )

[MohammadReza.OmidAllah]

سلام من این یه خطا رو هر کاری میکنم درست نمیشه فردا 8 صبح هم باید تحویل بدم اینو http://forum.majidonline.com/majidonline/smiley_new/majidonline_cry.gif میشه اگه کسی هست اینجا کمک کنه ؟

سوال: آرايه ي يک بعدي پويا با استفاده از کلاس تعريف نموده به گونه اي که شامل سازنده معمولي ، سازنده ي کپي ، == ، = ، =+ ، * باشد
