دوستان عزيز اين برنامه ها توسط آقاي مرتضي ظفري نوشته شده
خودشون اينها را در اينترنت قرار داده اند تا همه استفاده كنند
اميدوارم همه از ايشون ياد بگيرند و به جاي كمك معلم خصوصي به ديگران معرفي نكنند.
لطفا علامت ها را بر عكس كنيد و اگر در خواندنش مشكل داريد به من ميل بزنيد تا فايل اصلي را برايتان ارسال كنم
متاسفانه سايت اين آقا يادم نيست تا بهتون معرفي كنم
برنامه هایی از قبیل:
ساخت ماتریس همسازه از یک ماتریس وارد شده،
پیدا کردن تمام حالات مجموع دو عدد اولی که عدد دلخواه زوج را میسازند،
فاکتوریل یک عدد به کمک بازگشتی،
چند نوع مرتب سازی (نام و اعداد)
