Problem:

This program will read in a large US Coast Guard database of ship position information from the Automatic Identification System (AIS)1. The student provided functions will:

1. Prompt the user for the filename and open the file.

2. Read in data from the file into the vector database.

3. Prompt the user for a name/phrase to find in the vessel names.

4. Build a vector that contains unique vessels that contain the name/phrase.

5. If the number of vessels found is not zero, prompt to see if the user wants to display the

   vessel records whose names contain the phrase. If yes show records.

1. Prompt the user to see if they want to calculate the distance traveled? If yes, do

calculation and display distance. 6. Go to step 3 until quit is requested.

C++

I need help writing the functions. Please take your time. Let me know if you need more pictures. I cannot type all my code bc chegg only allows limited characters. Please take your time.

You must use getline() to read the data from the file with a ' ' as the terminating character. Once the line of data has been read, use getNextField() to parse the line, one field at a time. The initial call after the getline() should have the index set to zero, so it starts at the beginning of the string. getNextField() will update the index, so it won't need to be reset to zero until after the next call to getline(). The data should be read until end of file is reached. See example output. The function should start with a locally declared and initialized AISType temporary record. As the line is read/parsed and the fields are parsed, set the corresponding value in the temporary record. Once parsing the line is complete, and the temporary record is filled, use push_back() to add the temporary record to the AISType vector. Reset all values in the temporary record to default before reusing the temporary record on the next line. The function must keep a counter of the number of records read. The counter is used for outputting the number or records read. readFile() uses the following C++ functions getline() - C++ library getNextField() - student provided saveField() - student provided Algorithm for readFile() 1. use getline() to read the line into a string 2. check for eofo 3. set index to 0, fieldNumber to 0 4. call getNextField() on the string read in 1, passing index, and a string to receive the field 5. use saveField() to store the data in a temporary struct of type AISType (use fieldNumber to determine which field gets the data) 6. increment fieldNumber 7. loop back to 4 until the entire string has been processed. 8. add the temporary struct holding the data to the vector using .push_back() 9. reset fieldNumber and index to 0 10. loop back to 1 till eof() To get the progress count, place the following code at the bottom of the read loop. // Output the number processed. If the number update stops, then // their may be problem with the program. char eraseLine[]={" ',27,'1','1','K'}; if( (count % 100000) == 0){ cout & dataBase, string vesselName, vector & matchesAIS ); vector & dataBase - The database of AIS records read from the file string vesselName - the string to be searched for in the vessel names. vector & matches AIS all vessel whose names contains the passed string, vesselName, should have their MMSI string added to the passed vector matches AIS. matchesAIS is a vector that only contains the MMSI of vessels. return value the number of records found that match the passed string, vesselName. This function performs a linear search on all records in dataBase for records whose vesselName member contains the string passed in vessel Name. The search should be done from 0 to maximum valid index. This function calls addUniqueString() to add the MMSI to the matchesAIS vector. string makeStringUpper( string s); string s - the string to be converted to upper case. return value - upper case version of passed string. double string Convert(string s) string s 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. int findLastOccurrance(string mmsi, vector &d) string mmsi - the mmsi value being searched for vector &d the vector being searched. return value the index of the last record in the vector that contains the mmsi value passed in. This function performs a linear search to locate the last record in the passed vector with the specified MMSI. For efficiency, the search should be started at the last element and work toward the first. int findFirstOccurrance(string mmsi, vector &d) string mmsi - the mmsi value being searched for vector &d the vector being searched. return value the index of the first record in the vector that contains the mmsi value passed in. This function performs a linear search to locate the first record, in the passed vector, with the specified MMSI. The search should be started at the first element and work toward the last. void addUniqueString( vector &s, string value) vector &s the vector that the string should be added to string value the string to be added This function first searches the vector to determine if the string in already present. If the string is already present, the function simply returns. If the string is not present, the it is added at the end of the vector. A string will never appear twice in the vector. void saveField( int fieldNumber, string subString, AISType &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 saves the subString in to fieldNumber in the record passed, tempItem. The subString may need to be converted to a double, depending on the fieldNumber. See the definition of struct AISType for specific field data types. This function must use string Convert() to perform the conversion from string to double. A error message should be output from the function if an unknown field number is specified. double distance Traveled( vector & dataBase, int first, int last) vector & dataBase - vector containing the AIS data records int first - index of starting location record int last index of ending location record return value - calculated distance. In the case of a bad index value, 0.0 should be returned. Use the haversine formula to calculate the great circle distance between the vessel location in records first and last, using latitude and longitude.

You must use getline() to read the data from the file with a ' ' as the terminating character. Once the line of data has been read, use getNextField() to parse the line, one field at a time. The initial call after the getline() should have the index set to zero, so it starts at the beginning of the string. getNextField() will update the index, so it won't need to be reset to zero until after the next call to getline(). The data should be read until end of file is reached. See example output. The function should start with a locally declared and initialized AISType temporary record. As the line is read/parsed and the fields are parsed, set the corresponding value in the temporary record. Once parsing the line is complete, and the temporary record is filled, use push_back() to add the temporary record to the AISType vector. Reset all values in the temporary record to default before reusing the temporary record on the next line. The function must keep a counter of the number of records read. The counter is used for outputting the number or records read. readFile() uses the following C++ functions getline() - C++ library getNextField() - student provided saveField() - student provided Algorithm for readFile() 1. use getline() to read the line into a string 2. check for eofo 3. set index to 0, fieldNumber to 0 4. call getNextField() on the string read in 1, passing index, and a string to receive the field 5. use saveField() to store the data in a temporary struct of type AISType (use fieldNumber to determine which field gets the data) 6. increment fieldNumber 7. loop back to 4 until the entire string has been processed. 8. add the temporary struct holding the data to the vector using .push_back() 9. reset fieldNumber and index to 0 10. loop back to 1 till eof() To get the progress count, place the following code at the bottom of the read loop. // Output the number processed. If the number update stops, then // their may be problem with the program. char eraseLine[]={" ',27,'1','1','K'}; if( (count % 100000) == 0){ cout & dataBase, string vesselName, vector & matchesAIS ); vector & dataBase - The database of AIS records read from the file string vesselName - the string to be searched for in the vessel names. vector & matches AIS all vessel whose names contains the passed string, vesselName, should have their MMSI string added to the passed vector matches AIS. matchesAIS is a vector that only contains the MMSI of vessels. return value the number of records found that match the passed string, vesselName. This function performs a linear search on all records in dataBase for records whose vesselName member contains the string passed in vessel Name. The search should be done from 0 to maximum valid index. This function calls addUniqueString() to add the MMSI to the matchesAIS vector. string makeStringUpper( string s); string s - the string to be converted to upper case. return value - upper case version of passed string. double string Convert(string s) string s 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. int findLastOccurrance(string mmsi, vector &d) string mmsi - the mmsi value being searched for vector &d the vector being searched. return value the index of the last record in the vector that contains the mmsi value passed in. This function performs a linear search to locate the last record in the passed vector with the specified MMSI. For efficiency, the search should be started at the last element and work toward the first. int findFirstOccurrance(string mmsi, vector &d) string mmsi - the mmsi value being searched for vector &d the vector being searched. return value the index of the first record in the vector that contains the mmsi value passed in. This function performs a linear search to locate the first record, in the passed vector, with the specified MMSI. The search should be started at the first element and work toward the last. void addUniqueString( vector &s, string value) vector &s the vector that the string should be added to string value the string to be added This function first searches the vector to determine if the string in already present. If the string is already present, the function simply returns. If the string is not present, the it is added at the end of the vector. A string will never appear twice in the vector. void saveField( int fieldNumber, string subString, AISType &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 saves the subString in to fieldNumber in the record passed, tempItem. The subString may need to be converted to a double, depending on the fieldNumber. See the definition of struct AISType for specific field data types. This function must use string Convert() to perform the conversion from string to double. A error message should be output from the function if an unknown field number is specified. double distance Traveled( vector & dataBase, int first, int last) vector & dataBase - vector containing the AIS data records int first - index of starting location record int last index of ending location record return value - calculated distance. In the case of a bad index value, 0.0 should be returned. Use the haversine formula to calculate the great circle distance between the vessel location in records first and last, using latitude and longitude.
