C++ abnormal program termination

[jsmith1017]

Can someone look at this code and tell me what is wrong with it?

I get the message.....

abnormal program termination!

I think it has to do with the while loop and the Substr function.

If I take out the while loop it will work but only on one line.



Code....
#include <iostream>
#include <fstream>
#include <stdlib.h>
#include <string>
#include <iomanip>
using namespace std;

int main ()
{
string inf;
string ouf;

cout << "What is the input file?\n";
cin >> inf; // Input File Name
cout << "What is the output file?\n";
cin >> ouf; // Output File Name

string Field;
string s;

ifstream fin(inf.c_str());
ofstream fout(ouf.c_str());

while (fin){

getline(fin, Field, '\n');

s = Field.substr(5, 16);

fout <<s <<endl; //output last name

} //End while loop
fin.close();
fout.close();

return 0;
}

Without being able to compile and execute your program until I get home, ya I would take a look at that loop and your substr.

You have Visual Studio or another IDE? You should try out the debugger if you haven't already; it will be your new best friend.
