اشاره به اطلاعات وارد شده توسط کاربر و چاپ مجدد آن اطلاعات در صورت درست بودن

[u0.m1]

سلام ،
ورودی: کاربر میاد اطلاعات خواسته شده رو وارد میکنه ، و سپس باتوجه و انتخاب های موجود یکی از کلید های زیر را بزند
خروجی: تابع ریپورت و دو تا تابع سرچ با توجه به خواست کاربر
(این برنامه رو با آرایه نوشتم ، ولی خواستم یه بار با رشته (string) امتحان کنم ، که چون مثله اینکه خیلی ساده تر میشه)
ممنون میشم به من تو قسمت تابع void isbn_search() کمک کنید ، وقتی دستور if ، درست است ، برنامه فقط cout هارو برمیگردونه در صورتی که میخوام cout هارو به علاوه اطلاعات وارد شده قبلی برگرداند.
