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

  Pakistani journalists rally on the occasion of World Press Freedom Day in Karachi, Pakistan, May 3, 2018. The report, Press Freedom Barometer 2018, published ahead of Thursday’s observance of World Press Freedom Day, documents more than 150 violations against journalists and media groups in the country. The 16-page report’s violations include officially enforced censorship, written or verbal threats, killings, harassment, arrests, abductions, illegal confinements and physical assaults, conducted by state and nonstate actors and political and religious parties. “At least 157 cases of attacks and violations were documented in Pakistan between May 1, 2017, and April 1, 2018, across all four provinces, Islamabad and tribal areas. That’s an average of about 15 cases of violations a month,” the report noted. The executive director of Freedom Network, Iqbal Khattak, told VOA that despite a noticeable decline in overall terrorism in the country, journalism and journalists have remained v...

  Write down about at least three companies which were the victim of Computer or Internet crime. Apple Company:   Apple's iPhones enjoy a reputation for being ultra-secure and hard to hack, so most cybercriminals don't bother trying. However, you shouldn't think of your iPhone as a device that's totally safe from hackers. In February, a team of researchers at Google alerted Apple to vulnerabilities that persisted for two years and allowed hackers to embed malware on iPhones after people visited particular websites. What Happened? Even though researchers at Google found these issues months ago and reported them to Apple at that time, the team  only recently went public  with the discoveries. They revealed five so-called exploit chains that link security vulnerabilities together and allow hackers to get through each layer of the security protections built into an operating system. The exploit chains took advantage of 14 total security flaws that allowed cybercrim...
