firstly, to send to a function I would use a pointer(IMO), and for in the infile you need to do alot more than just infile here is a sample from an old code I did(some things have been deleted for the sample :P)
Code:
#include <iostream>
#include <fstream>
#include "foodClass.h"
using namespace std;
void Food::readFile()
{
int length = 0;
foodFacts foodCapacity;
foodCapacity.name = new char [101];
foodCapacity.catagory = new char [50];
ifstream readIn;
head = NULL;
readIn.open("fooddb.db");
if (! readIn) {
cerr << "There was an error opening the data." << endl;
exit(1);
}
readIn.get(foodCapacity.name, 100, ';');
readIn.ignore(1000, ';');
while ( ! readIn.eof() ) {
readIn.get(foodCapacity.catagory, 100, ';');
readIn.ignore(1000, ';');
readIn >> foodCapacity.calories;
readIn.ignore(100, ';');
}
readIn.close();
}

I'm still having problems with calling the functions. How am I supposed to use a pointer?
My array is 10 elements long. The function I'm calling will load the array with data from a file. Maybe somebody could show me how to call a function with an array as a parameter?? I really don't what I'm doing wrong.
