Trying to read in a txt file.. line by line

//main.cpp
#include <iostream>
#include <fstream>
#include <stdio.h>
#include <string>
using namespace std;

int main()
{
	fstream reader;
	string c[9];
	int counter = 0;
	
	reader.open("test.txt");
  
	if(reader)
	{
    
		while(!reader.eof())
		{
			
			
			getline(reader, c[counter], ".");
			cout << c << endl;
			counter++;
			
			if(counter == 9)
				break;
			
		}
		
	}
	else
	{
		cout << "Couldn't find the file \n";
	}
  
}
