Input/Output help

[GoPredsGo]

I am at a point that I have no idea what to do. See my code below. The program will not open my mail.dat file that I am supposed to use to get the output of just the email address's on it that outputs to another file "address.dat" I think my code is right but I get nothing, any advice, thanks


// This programs outputs email address's that have the "@" symbol in them

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()

{
ifstream inData;
string tempString;
ofstream outData;

// Open Data Files
inData.open("mail.dat");
outData.open("adresses.dat");
// Press enter to get the output to an external file
cout << "Please press enter for email address's" << endl;

// Test if file is there
if (!inData)
{
cout << "If mail.dat can not be found program will close" << endl;
cin.get();
cin.get();
return 1;
}

while(inData)

{
inData >> tempString;
if(tempString.find('@') != string::npos);
outData<<tempString;
}

// Output Results
outData << "Email addresses:" << endl;

// Close Files
inData.close();
outData.close();

cin.get();
cin.get();
return 0;
}

if you do this:

inData.open("mail.dat");

you're trying to open that file from the current path. So you need to know where the current path is. Usually somwhere near the .exe (if it's windows)
