Reading lines from a file.

Hi,

I wrote a function where I want to read 2 lines from a file. Each line will be soimething like

A + B - C
A - B + A - D - F

etc

I wrote a function as follows:

Code:

---

void GetData(string& Infix, string& Pre)
{
  ifstream ins;
  ins.open("data.txt");
  char buffer[80];
 
  int Count = 0; // Counter used to update position in array where we are saving the floppies contents to.
 
  string data;
  string FloppyData[2];
 
  while(!ins.eof()){
    getline(ins,data);
    FloppyData[Count] = data;
    Count++;
  }
 
  Infix = FloppyData[0];
  Pre = FloppyData[1];
 
}

---

I can't see whats wrong with it. I want the FloppyData array to hold two strings, then assign Infix and Pre to the right values in the array.

Thanks in advance for any feedback.

All I did to get your code working is specified an absolute path to the file

Code:

---

#include "iostream"
#include "string"
#include "fstream"


using namespace std;

void GetData(string& Infix, string& Pre)
{

  ifstream ins("c:\\data.txt");
 
 
  int Count = 0; // Counter used to update position in array where we are saving the floppies contents to.
 
  string data;
  string FloppyData[2];
 
  while(!ins.eof()){
    getline(ins,data);
    FloppyData[Count] = data;
    Count++;
  }
 
  Infix = FloppyData[0];
  Pre = FloppyData[1];
 
}


int main()
{
        string i,p;

        GetData(i,p);

        cout << i << endl;
        cout << p;

        system("Pause");

        return 0;

}

:( I can compile that, but when I try to run it comes up with a pop up message saying - btw, I wouldn't have a clue where the created error log is.

Program Error

file.exe has generated errors and will be closed by Windows.

An error log is being created.
