Write a back–end class called CSVFileLoader and save it in a file called CSVFileLoader.cpp. This class must have the following structure: Private Members Data Type Name Description boolean cFileReadSuccessful This member will indicate if the file-read operation was successful. Private Methods Return Type Method Signature Description int determineNumberOfColumns(string fileName) This method must determine the number of columns in the file. Insert a debug instruction that will display the number of columns as the method exits. void splitData(string line, TUTCell data[]) This method must split the line into separate elements and store each element in the data[] array. Insert a debug instruction that will display the data content of each element as it is inserted into data[] array. Public Methods Return Type Method Signature Description TUTTable loadFile(string fileName, string subjectCode) This method must load the data of the file into a table object. Only students with the same subject code as indicated by the subjectCode input argument may be added to this table. At the completion of this method it must return the populated table. Hint: Make use of the determineNumberOfColumns() and splitData() methods in this method. At the beginning and end of this method insert similar debug instructions as those in the copy constructor of the TUTTable class. Also insert a debug instruction that will display the content of each line as it is read from the CSV file. boolean readSuccessful() This method must indicate if the read process was completed successfully by returning true or false.

Private Members
Data Type Name Description
boolean cFileReadSuccessful This member will indicate if the file-read operation was successful.
Private Methods
Return Type Method Signature Description
int determineNumberOfColumns(string fileName) This method must determine the number of columns in the file.
Insert a debug instruction that will display the number of columns as the
method exits.
void splitData(string line, TUTCell data[]) This method must split the line into separate elements and store each
element in the data[] array.
Insert a debug instruction that will display the data content of each element
as it is inserted into data[] array.
Public Methods
Return Type Method Signature Description
TUTTable loadFile(string fileName, string subjectCode) This method must load the data of the file into a table object. Only students
with the same subject code as indicated by the subjectCode input argument
may be added to this table. At the completion of this method it must return
the populated table.
Hint: Make use of the determineNumberOfColumns() and splitData() methods
in this method.
At the beginning and end of this method insert similar debug instructions as
those in the copy constructor of the TUTTable class. Also insert a debug
instruction that will display the content of each line as it is read from the CSV
file.
boolean readSuccessful() This method must indicate if the read process was completed successfully by
returning true or false.
