mitchell is on a distinguished road

mitchell is offline
when I run this I get a bus error.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

// Forward Declarations

//Post: opens file fname, reads file, returns an dynamic arrary of integers
// arrSz is passed by reference to keep track of size of dynamic array
void readData(string fname,int & arrSz);

int main (int argc, char * const argv[]) {
int filesize = 0;

readData("example.txt", filesize);

return 0;

// Reads contents of file into an array
// returns array, arrSz records the array size
void readData(string fname, int & arrSz){

//Declare Variables
int* result = NULL;
arrSz = 0;
int temp;

//Create a file object and open the file
ifstream inStream;;

//only process file if opening it is successful
//find out how big the file is
inStream >> temp; //reads line intotemp and moves to the next line

//admin functions to refresh file

//Read file contents into result, now that size is known
result = new int[arrSz]; //creates results array

//reads contents into array
for(int i; i < arrSz; i++){
inStream >> result[i];
cout << result[0];

I think the problem is in the argument "example.txt" When I get rid of the string fname parameter and just put the file name directly into then it works fine. Any ideas?

QUOTE Thanks
