امیدوارم آموزش قبلی برای شما مفید واقع شده باشه در این سری از حل تمرین برنامه نویسی ++C  با توجه به اینکه  پایان ترم دانشگاها می باشد و بیشتر اساتید به دانشجویان خود پروژه پایان ترم داده اند ما در این سری بیشتر مثال های را ارئه داده ایم که احتمال داده شدن آنها به عنوان پروژه زیاد است . در سری قبلی آموزش ما  به برنامه های دفترچه تلفن ، برنامه برج هانوی ، مرتب سازی سریع و برنامه ای که پس از اجرای آن موشکی در صفحه نمایش ایجاد شده و به بالا حرکت کند پرداختیم. باز هم یادآوری می کنم اگر شما تمرین خاص دارید و به جواب آن نیاز دارید کافیست صورت مسئله مورد نظر خود را از طریق قسمت دیدگاه این مطلب به ما بدهید تا در سری بعدی آموزش جواب آن را به شما ارائه دهیم.(در صورتی که سریع به جواب خود نیاز دارید جواب آن را به ایمیل شما ارسال می کنیم. البته این احتمال وجود دارد که با توجه به امتحانات جواب سوال تان را با تاخییر دریافت کنید.)
