سورس کد مدیریت فروشگاه به زبان سی پلاس پلاس

در این پست سورس کد پروژه مدیریت فروشگاه به زبان برنامه نویسی سی پلاس پلاس رو آماده کردیم که در محیط Borland C++ برنامه نویسی شده است باید اینو متذکر شوم برای اجرا از نرم افزار مشخص شده استفاده کنید و این که می توانید از این نمونه کدها برای یادگیری بیشتر استفاده کنید و نکات آموزشی فوق العاده ای در این پروژه ها وجود دارد .

سی پلاس پلاس :
++C (بخوانید سی پلاس‌پلاس) یک زبان برنامه‌نویسی رایانه‌ای همه‌منظوره، شیءگرا، سطح بالا و چندرگه (که از برنامه‌نویسی رویه‌ای، تجرید داده‌ها و برنامه‌نویسی شیءگرا پشتیبانی می‌کند)، عمومی و با قابلیت‌های سطح بالا و سطح پایین می‌باشد. این زبان دارای قابلیت‌های انواع داده ایستا، نوشتار آزاد، چندمدلی، معمولاً زبان ترجمه شده با پشتیبانی از برنامه‌نویسی ساخت‌یافته، برنامه‌نویسی شیءگرا، برنامه‌نویسی جنریک است. از آنجا که در سی++ اشیاء را می‌توان ابتدا به ساکن از کلاس‌هایی ایجاد کرد که به هیچگونه سلسله مراتب رده‌ها و وراثت مقید نیستند، لذا سی++ از برنامه‌سازی شیء بنیاد (object-based programming) نیز پشتیبانی می‌کند. ++C به همراه جد خود C از پرطرفدارترین زبان‌های برنامه‌نویسی تجاری هستند.

++C یک زبان سطح میانی در نظر گرفته می‌شود؛ این زبان دارای قابلیت زبان‌های سطح بالا و پایین به‌صورت هم‌زمان است.

++C توسط بی‌یارنه استراس‌تروپ ریاضیدان دانمارکی در سال ۱۹۷۹ در آزمایشگاه‌های بل (Bell Labs)، برای بهبود زبان سی و بر مبنای آن ساخته شد و آن را «C با کلاس» (C With Classes) نام‌گذاری نمود. در سال ۱۹۸۳ به ++C تغییر نام داد. توسعه با اضافه نمودن کلاس‌ها و ویژگی‌های دیگری مانند توابع مجازی، سربارگزاری عملگرها، وراثت چندگانه، قالب توابع، و پردازش استثناء انجام شد. این زبان برنامه‌نویسی در سال ۱۹۹۸ تحت نام ISO/IEC ۱۴۸۸۲:۱۹۹۸ استاندارد شد. نسخهٔ فعلی استاندارد این زبان ISO/IEC ۱۴۸۸۲:۲۰۱۴ است.
