Ayuda codigo con clases.

Hola muy buenas, estoy diseñando un codigo con clases pero al compilarlo me da error, a ver si alguien me puede echar una mano y ayudarme a solucionarlo.

Main:

Código:

#include <iostream>
#include <fstream>
#include <string.h>
#include<string>
#include<stdio.h>
#include <stdlib.h>
#include "info.hh"
#define MAX_CUSTOMERS 30

using namespace std;
int main(){
	info group[MAX_CUSTOMERS]();
	info aux();
	int index = 0;
	int proba;
	int i =0;
	string read_line;
	ifstream myfile ("30");
	if (myfile.is_open())
	{
		while ( getline (myfile,read_line) )
		{
			aux(read_line);
			group[i] = aux;
			i++;
		}	
		myfile.close();
		proba = group[i].getNumber;
		cout << proba << endl;
	}

	else{
		cout << "Unable to open file"; 
	}
	return 0;
}

Header:

Código:

#include <iostream>
#include <fstream>
#include <string.h>
#include <string>
#include <stdio.h>
#include <stdlib.h>

using namespace std;

class info {
	public:
	info(string);
	int getNumber();
	private:
	int phone;
	char *name, *email, *city;
	
};

Clase

Código:

#include <iostream>
#include <fstream>
#include <string.h>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include "info.hh"
using namespace std;

 
	
info::info(string line) {
		
		char s[line.size()+1];
		strcpy(s,line.c_str());		
		char *token = strtok(s,",");
		
		name = token;
		token = strtok(NULL,",");
		city=token;

		token = strtok(NULL,",");
		email=token;	

		token = strtok(NULL,",");
      		phone= atoi (token);
}
int info::getNumber(){
	return phone;
}
