Oop(Object Oriented Programming) Project for final year students

 

Project Description:

Write the C++ Code for the following parts                                                  

A.    Create a class Product. Also create two descendants (derived from Product class) Food and Clothes.

B.     The class Product must have a data members Product_Id, Price and Name. It contains a constructor to initialize the data members and “getdata ()” method to store the values in data members.

C.     The class " Clothes " will have additional data members Color. The Clothes class also contains a constructor to initialize the data members and “getdata ()” method to store the values in data members. It additionally contains

·         storedata () method to store data in file named as “Clothes.txt”

·         readdata () method to read all information from this file

·         deletedata () to delete specific product from file

·         updatedata () to update any record

·         searchdata () to search the details of specific product entered by user.

D.    Make sure duplicate Product_Ids should not be entered in files

E.     Create separate header files for each class

F.      Write a menu-driven program using the Switch case and do while to select any choice from multiple option to obtain desired result
