CSVReader

CSV Reader File Management

This is a small and easy to use library to Read small CSV files.

Motivation

I'm working on an academic project that depends on taking data from a CSV file. So I thought about making a library that serves this purpose and develop it in the learning road.
So, In version one (V1) this library serves this project in the first place.

C++ Version

C++11 is the minimum version required.

Getting Start with small Example:

#include "CSVReader.h"  
#define FILENAME "fileName.csv"
using namespace std ;  
int main(){  
  CSVReader in (FILENAME);  
  string str_Data[50];  
  //Print All Data in CSV file
  in.printCSV();
  // Get Data from specific column and indexing it in string array
  in.getCol(1,str_Data);
}

Documentation:

The libary provides one class:

Class	Usage
CSVReader	It's a CSV file management class that helps you to handle small CSV file extension.

Methods

Method Name	Usage	Parameter	return	Example
CSVReader(string)	CSVReader Constructor that open file and initialize some attributes.	string - string contains filename with extension.	void	Here
setRowDelimeter(char)	Set Row Delimeter for CSV file. By default is \n.	char - Take single character represent Delimeter.	void	Here
setColDelimeter(char)	Set Column Delimeter for CSV file. By default is ,.	char - Take single character represent Delimeter.	void	Here
getfileName(void)	Get Working File Name.	void	string - String contains file name.	Here
printCSV(void)	Print All CSV file Information.	void	void	Here
getNumOfCols(void)	Get Number of Columns in CSV File.	void	int - Number of Columns in CSV file	Here
getNumOfRows(void)	Get Number of Rows in CSV File.	void	int - Number of Rows in CSV file	Here
getCol(int,string)	Read Specific Column from CSV file and indexing it on array (every cell in index).	int- integer number represent number of Column. string string_resultArr[] - String array holds the result.	void	Here
getRow(int,string)	Read Specific Row from CSV file and indexing it on array (every cell in index).	int- integer number represent number of Row. string string_resultArr[] - String array holds the result.	void	Here
closeFile()	Close Working File.	void	void	Here
~CSVReader()	CSVReader Destructor that close file.	void	void

Examples

Constructor-Initialization

CSVReader:: CSVReader(string string_fileWithExten)
{
	fileName = string_fileWithExten;
	fin.open(string_fileWithExten);
	numberOfRow = 0;
	numberOfCol = 0;
	COL_delimeter = ',';
	ROW_delimeter = '\n';
}

In-main

#include "CSVReader.h"  
using namespace std ;  
int main(){  
 // Make Object from CSVReader Class
  CSVReader in ("fileName.csv");  
  // Re-set Row and Column Delimeter
  in.setRowDelimeter('\n');
  in.setColDelimeter(',');
  // Print File Name On Console screen
  cout << in.getfileName() << endl;
  // print All Info. on Console screen
  in.printCSV();
  fin.closeFile();
}

Example-2

Print CSV file Column by Column using getCol(int,string) and getRow(int,string)

#include "CSVReader.h"  
using namespace std ;  
int main(){  
 // Make Object from CSVReader Class
  CSVReader in ("fileName.csv");  
  string str_Data[50];
  int numberOfCols = in.getNumOfCols();
  int numberOfRows = in.getNumOfRows();
  for(int i = 1 ; i <= getNumOfCols ; i++)
  {
    getCol(i,str_Data);
    for (int j = 0 ; j<numberOfRows ; j++)
    {
      cout << str_Data[j] << " ";
    }
    cout << endl ; 
  }
}
// Desstructor will close file auto.

Desstructor

CSVReader :: ~CSVReader(void)
{
	fin.close();
}
