Problem: This program will implement the same functionality as Assignment 1, but as a C++ class. The class definition is provided and should not be modified except as specified. Refer to the Assignment 1 write up for program functionality. AISClass - makeStringUpper( string s): string - getNextField(string &line, int &index, string &sub String): bool distance Traveled( int first, int last) : void - findLast Occurrance(string mmsi ) : int findFirstOccurrance(string): int - stringConvert( string): double - addUnique String( string value) : void - saveField( int fieldNumber, string subString, AISType &tempItem ): void openInputFile(ifstream &): bool - readFile( ifstream &): void AIS Data : vector - uniqueMmsi : vector - recordCount : int + printRecord( int) : void + searchForVesselByName ( string vesselName) : int + AISClass() + AISClass + readDataBase() : void + new Search(): void Detailed Function Descriptions void readFile( ifstream & inFile) inFile - already open file to be read This function performs similarly to the version from assignment 1, but stores the data in the class variable vector AISData, and the count is saved in member recordCount. The same algorithm may be used to parse the file or students may implement their own algorithm. Optional bool getNextField(string &line, int &index, string &subString) string &line - the line of data read from the file that needs to be parsed int &index the current starting position of the parsing. The first time this function is called for a new line, index should be set to zero. The function should update the index before returning, so that on the next call it will look at the next field. string &subString - the parsed string return value - true if more data is available, false if the whole string has been parsed. This function is the same as in Assignment 1, but is a member of the class now. This function may be omitted if students develop their own algorithm to parse the input data file. bool openInputFile( ifstream& inFile ) ifstream& infile - file stream variable for the file to be opened. This function is the same as assignment 1 but a member of the class now. void printRecord( int record Number ) int record Number The element number of the record to print from AISData. The function is similar to the version from Assignment 1, but is passed the element number instead of the record itself. All fields for the record are printed. See example output for formatting. int searchForVesselByName( string vesselName) string vesselName the string to be searched for in the vessel names return value the number of records found that match the passed string, vesselName. This function is very similar to Assignment 1 but is a member of the class now. The function searches the member vector, AISData for possible matches, and adds vessels found to the member vector unique Mmsi by calling addUnique String(). string makeString Upper( string s) string s - the string to be converted to upper case. return value - upper case version of passed string. This function converts the passed string to upper case and returns it. The library function toupper() may be called by this function. This is the same as Assignment 1 but is now a member of the class. double string Convert(string s) strings - the string to be converted into a double return value - the double converted from the string This function converts a string to it's corresponding double value. Implementation of the function must use string stream. All other implementations are not allowed and will have significant point deductions. This is the same as assignment 1 but now is a member of the class. int find LastOccurrance(string mmsi) string mmsi - the mmsi value being searched for return value - the index of the last record in the vector that contains the mmsi value passed in. This function is very similar to the Assignment 1 function, but searches the member vector AISData for the matching vessel. int findFirstOccurrance(string mmsi) string mmsi the mmsi value being searched for return value the index of the first record in the vector that contains the mmsi value passed in. This function is very similar to the Assignment 1 function, but access the member vector AISData for the matching vessel. void addUniqueString( string value) string value - the string to be added This function is very similar to the version from Assignment 1, but adds the string to the member vector uniqueMmsi. Optional void save Field( int field Number, string subString, AIS Type &tempItem ) int fieldNumber - the number of the field, starting at zero string subString - the value to be saved in the field, may require conversion to double inside the function. AISType &tempItem- the record to which the field will be added This function is the same as Assignment 1. If students choose to implement their own algorithms to parse the data, this function may be omitted. void distance Traveled( int first, int last) int first - index of starting location record int last - index of ending location record This function is similar to the version from Assignment 1, but access the member vector AISData to retrieve the values used for the distance calculation. The function also output the distance calculated. Functions New in Assignment 2 void newSearch This function handles a large part of what was handled by main in Assignment 1. After the file has been open and read in, all user interaction occurs in this function. The user is prompting for the vessel name to be searched for, exiting if 'q' is entered, calling searchFor VesselByName(), asking the user if they want to see the first record for the vessel, calling printRecord() if required, asking if they want to calculate the distance, and calling distance Traveled. Notes: This function loops until the user enters 'q' at the prompt for the vessel name to search for. The member vector unique Mmsi should be cleared at the beginning of a new search. AISClass() The default constructor for the class should initialize member recordCount to zero. -AISClass() The default constructor should clear both member vectors, AISData and uniqueMmsi. The message "Memory returned for vectors" should be output. void readDataBase() This function performs a portion of what was done in main() in Assignment 1. It calls openInputFile(), and exits the program if a false is returned from the open function. If true is returned, then readFile() is called to read the data into the member AISData, lastly the number of records that were read is output.
