Assignment Specification: your program should include the following: • Functions (should include both: pass by value and pass by reference variables, void function and function returning any value) • Array of structs (at least one single array of struct) • Selection and repetition structures as needed • Add your team members names as a comment in the first line of your program. • You should print a menu to the user and offer him/her different services. • Main Services: o adding new item o search for specific item. o update existing record delete. Sort o Display At the start, your program should populate the array(s) from a file and allow the user to edit it. At the end overwrite the same file with the latest contents of the array(s). Provide another statistical report as separate text file e.g. the number of records, with date, time of last update. • The program should continue running until the user chooses to exit it. • Ensure to avoid any errors of any type (Run-time error, logical error, and syntax error). • You can add extra functions if wish to
Criterion Description Functions Files Array and struct 3 3 اليا 0.75 Your functions should show how it helped you to develop more reusable and readable program. Each Functions function should serve correctly to achieve your system Declaration & Call goals. You should use functions overloading and extra methods to achieve your goal. Variables, Struct Effectively make use of arrays including array of struct in your program(s). This include both local and global & Arrays variables. Those arrays should be easily browsed and Declaration searched. Reading from / Successful file access for reading and writing Writing to file Comprehensible, well-documented and well-structured 3 Program Structure programs. Organization of code delivery and quality of code. Expected users' errors should be handled well through: • Using a proper in-depth analysis of all users' Error Handling input and limiting all users' invalid entry. • Handling all expected run-time errors. Successful live demonstration of your working application. Working Demo, • Clear separation of functions; maintainable code; validation Evaluation, Delivery, & Evaluation of the effectiveness of your approach.

Project(Library) • We are going to use the following file structure line#1 is Book ID - books.bit - Notepad File Edit Format View Help 1234 Never Gonna Give You Up Rick Astley 4.5 AAA Thriller 6532 yyyyy bbbbbb Line #2 is Title Line #3 is Artist 7
Creating A struct Structure is called library and contains the following members o Id, title and artist #include <iostream> #include <fstream> using namespace std; struct Library { string id; string title; string artist; }; string fileName =""; string bFileName=""; const int LIMIT = 10; int size=0;
. . Load Data Function : This function loads data form file to array of struct - Name : LoadData Return type: void why we used void? Formal parameters: array of struct , file Name. what is the call type for array of struct is it by refence or by value! oid loadData(string fName, Library lib[]) ifstream inFile; nFile. open (EName.c_str(), ios::in); f(infile.is open() == true || inFile.is open()) ! int counter=0; while (!inFile.eof()) { getline (inFile, lib[counter].id); getline (inFile, lib[counter].title); getline (inFile, lib[counter].artist); counter++; } size=counter-1;} Ise {cout<< "Failed or File is not exist\n";) File.close(); } 9 OD
Project(Library) DisplayData: This function print out the array ofstruct (books data on the screen) IDE 1234 Atle: llever Gonna Give You Up - Name: displayData Artist: Rick Astley 4.5 Return type: void Title: All Formal parameters: array of struct Artist: Thriller 6532 LO: - 10: Title: yyyyy Artist: bbbbbb void displayData (Library lib[]) Process exited after 0.1725 seconds with return value o Press any key to continue... for (int i=0;i<size; i++) { cout << "ID: "<< lib.id << "\n"; cout << "Title: "<< lib.title << "\n"; cout << "Artist: "<< lib.artist << "\n"; } } > 10
Project(Library) saveDatatoFile: This function save data to output file that means data each time data will be erased and printed to the file to ensure that lastest updates is saved 1234 Name : save Datato File Never Gonna Give You Up Return type: void Rick Astley 14.5 Formal parameter: File Name array of struct AAA void saveDatatoFile(string fName, Library lib'l) Ler (ofstream File; 6532 oFile.open (fName.c_str(), ios::out); yyyyy if (ofile.is open() = true || File is open()) { bbbbbb for (int i=0;i<size;i++){ File « lib.id << "\n"; oFile « lib.title << "\n"; oFile « lib.artist << "\n"; } File.close(); cout << "\nData Saved successfully\n"; ) 1 11
Project(Library) addBooks: In this function user Enter data of the book and saved to directly to a file, note that the file is opened in append mode and user will keep enter values until he decides to exit Name : addBooks - Return type: void - Formal parameter: File Name 12
Project(Library) void addBooks (string fName) { ofstream appFile; appFile. open (FName.c_str(), ios :: app); string bookID. title, artist; int choice; if (appFile.is open() == true || appFile. is open()) { do { cout<<"Enter Book ID\n"; cin>> bookID; Enter Book ID cout<< "Enter Title\n"; 12333 cin>> title; Enter Title cout<<"Enter Book Artsit\n"; Codinding in C++ cin>> artist; appFile << bookID <<"\n"; appFile « title <<"\n" ; appFile<<artist < "\n"; cout << "Enter -1 to extit\n"; cin >> choice ; } while (choice!=-1); appFile.close(); cout<< "Books added successfully\n"; } }
Project(Library) : deleteBookByID: in this function user will enter the book ID of the books he wants to delete, if the book is not found a prompt will tell the user that book is not found, after deleting, user has to save data to file using function save DatatoFile in (slide #9) and to print data using function display Data in (slide #8). Note : array of struct is treated like normal array- Enter Book ID you want to delete Name : delete Book ByID 1.23 Return type: void pook not found Formal parameter: array of struct Process exited after 3.593 seconds with return value 8 Press any key to continue ... - Write two versions of this function: 1. Following sequential search algorithm by implementing the sequential search in a function and call the function from deleteBook ByID by sending the array of struct and the required ID: int Sequential SearchForID (Library lib[], int id) 2. Following binary search algorithm implementing the binary search in a function and recursively call the function from delete Book ByID by sending the array of struct and the required ID, low index and high index, int BinarySearchForID (Library lib[], int id, int low, int high) 14 a a I
Project(Library) sortDatabyTitle: In this function Data will be sorted in descending order based on book title.

Project(Library) • In the main program functions are called, it would be better if display menu function is created that allow the user to enter the process he wants to do by using switch statement. This can be done by adding displayMenu function to enhanced the application. Starts the main by declaring the array of struct and file names: const int LIMIT = 1000; Library database (LIMIT); int size=0; String fileName="books.txt", bFileName="books_backup.txt"; Calls to all discussed functions can be : loadData(fileName, database); displayData (database); saveDatatoFile(fileName, database); sortDatabyTitle (database); displayData (database); backupData (fileName, bFileName); addBooks (fileName); deleteBookByID (database); saveDatatoFile(fileName, database); 18
