All requirements stated and illustrated in the excerpt from theSoftware Requirements Specification (see below) shall befollowed.
You will be required to meet ALL of the requirementsstated below.
2.1 System Organization
2.1.1
This program shall be implemented in C++ as a sorted (ordered)linked list. With nodes ordered by stock number.
2.1.2
The class used to store information on each book shall shall bethe BookRecord class developed in ProgrammingAssignment 1 with appropriate modifications so that it can be usedin a linked list.
2.1.3
All list functions shall be defined in a C++ class calledBook_Inventory. The class shall be defined asfollows:
//-----------------------------------------------------------------------------// File: Book_Inventory.h// Header file for a book inventory program implemented as a sorted linked list//// Note: All functions which print data on a book must print an appropriate// message if it fails to find any book(s) meeting the search criteria//-----------------------------------------------------------------------------#pragma once;#include // This header lets you use cout and cin#include // This header gives you all the file I/O functions#include#include#include \"BookRecord.h\"using namespace std; // This command lets you use all the I/O function and include headers w/o the \".h\"class Book_Inventory{ private: BookRecord *m_pHead; // Pointer to the head of the list ifstream m_InFile; // File containing the inventory public: Book_Inventory(); // Class constructor ~Book_Inventory(); // Class destructor. Must free all list memory void ClearList(); // Remove all items from the list bool readInventory(const char *filename); // Read inventory file and build the list bool addBook(BookRecord *br); // Add the given book to the list BookRecord *removeBook(long stockNum); // Remove a book from the list or print message if not found BookRecord *searchByStockNumber(long stockNum); // Search by stock number return pointer to node or NULL if not found void searchByClassification(int cl); // Search for all books given classification, print all data void searchByCost(double min, double max); // Search for all books within the given cost range int getNumberInStock(long sn); // Get number of books in stock for the given stock number void printAll(); // Print all information on all books in the inventory. private: bool getNextLine(char *line, int lineLen); // read next line from a file};
2.1.4
The BookRecord class shall have the private variableBookRecord *m_pNext, and the public functionsvoid setNext(BookRecord *next) andBookRecord *getNext() added to it
2.1.5
When data on a book is printed on the screen it shall be all ona single line in the following format:
   Title   Stock_Num   Classification   Cost   In Stock
   For example:
   Introduction toC++   12345   613   49.95   5
2.1.6
Format of the data file to be read shall be as follows:
   # Any line beginning with a pound sign shallbe ignored as a comment line
   # First non-comment line will give the number ofbooks in the file
   # Remaining lines will give the stock number,Title, classification,
   # cost and number in stock. Each shall be on aseparate line.
   # Example:
   25
   12345
   CS221 A Programming Challenge
   613
   23.95
   15
   # etc. for the remaining books in this list.
Note: Do not assume that the data file that will be usedto test your program will be the same as the exampleprovided.
2.1.7
Source code which can be adapted for use in the readInventory()function will be provided from the company Code Reuse Library.
2.1.8
The getClassification function in BookRecord shall be modifiedso that it functions as a \"normal\" get function, that isit shall return the classification value. Prototype the function asfollows:
     intgetClassification();
2.1.9
The getCost function in BookRecord shall be modified so that itfunctions as a \"normal\" get function, that is it shallreturn the cost value. Prototype the function as follows:
     doublegetCost();
Source Code Reuse Library
The following function fragment shows how to open a file andstart to read lines from the file
using the getNextLine() function. Either the Book_Inventory.h fileor the Book_Inventory.cpp
file will have to #include ,, and and include
the line using namespace std for this to work.
//--------------------------------------------// Function: readInventory()// Purpose: Read the inventory data file and// build the list.// Returns: True if successful read//--------------------------------------------bool Book_Inventory::readInventory(const char *filename){ char line[128]; int numBooks; // define other variables here as needed m_InFile.open(filename, ifstream::in); if(!m_InFile.is_open()) { // m_InFile.is_open() returns false if the file could not be found or // if for some other reason the open failed. cout << \"Unable to open file\" << filename << \"\nProgram terminating...\n\"; return false; } // Read number of books getNextLine(line, 128); numBooks = atoi(line); for(int i=0; iThe atoi() (Ascii TO Integer) function is foundin stdlib.h. It takes a string
(character array) as an argument. The string must be a stringrepresentation of an
integer value. For example: \"25\". The function then parses thestring and returns
the int value represented by the string. There are also two otherfunctions in stdlib.h
which may be useful. These are atof() (Ascii TOFloat) which returns a double
value and atol() (Ascii TO Long) which returns along value.
The following function can be added to your Book_Inventory class asa private function.
It uses a class variable called m_InFile that is a reference to anopen text file (opened by
the readInventory() function) and will read the next line from thefile storing it in the
character array pointed to by line which should be a minimum of 128characters in length.
The lineLen argument gives the length of the array.getNextLine() will skip any comment lines
(those starting with #) and blank lines. It returns an empty stringafter the last line in
the file has been read.
//--------------------------------------------// Function: getNextLine() // Purpose: Read a line from a data file.// The next non-comment line read from file// is stored in line char array.// An empty string is stored if the end of// file is reached.// Returns: bool - true if a valid line was// read, false if end of file is reached. //--------------------------------------------bool Book_Inventory::getNextLine(char *line, int lineLen){ int done = false; while(!done) { m_InFile.getline(line, lineLen); if(m_InFile.good()) // If a line was successfully read { if(strlen(line) == 0) // Skip any blank lines continue; else if(line[0] == '#') // Skip any comment lines continue; else return true; // Got a valid data line so return with this line } else // No valid line read, meaning we reached the end of file { strcpy(line, \"\"); // Copy empty string into line as sentinal value return false; } } // end while return false; // Cannot reach this point but include a return to avoid compiler warning // that not all paths return a value.}
