input/output files

[ironman]

im writing a program that uses data from a .txt file. i have been working on this code for quite awhile now and cant quite get it. i want the file to extract information from "funds.txt" which looks like this:

Harry & David Inc
50
12.99
19.85

i want the program to load the information from the file by typing "L" then display the information by typing "D"

so far this is what i got:

#include <iostream>
#include <iomanip>
#include <fstream>

using namespace std;

int main()
{
char answer;
fstream data;
string fundName = "";
int numberOfShares = 0;
double purchasePrice = 0, currentValue = 0;

cout << fixed << showpoint;
cout << left;

cout << setw(5) << " " << "Menu" << endl;
cout << setw(5) << "L" << "load from file" << endl;
cout << setw(5) << "D" << "display" << endl;
cout << setw(5) << "Q" << "quit" << endl;

cin >> answer;

while (answer != 'Q')
{
if (answer == 'L')
{
data.open("funds.txt",ios::in);
getline(cin, fundName);
data >> fundName; >> numberOfShares >> purchasePrice
>> currentValue;

}

else if (answer == 'D')
{
cout << fundName; << numberOfShares << purchasePrice
<< currentValue;
data.close();
}

cin.clear();
cin.ignore(200,'\n');

cout << setw(5) << " " << "Menu" << endl;
cout << setw(5) << "L" << "load from file" << endl;
cout << setw(5) << "D" << "display" << endl;
cout << setw(5) << "Q" << "quit" << endl;

}

system("pause");
return 0;
}

can someone please help me?

while (answer != 'Q')
{
if (answer == 'L')
{
data.open("funds.txt",ios::in);
getline(cin, fundName);
data >> fundName; >> numberOfShares >> purchasePrice
>> currentValue;

}

else if (answer == 'D')
{
cout << fundName; << numberOfShares << purchasePrice
<< currentValue;
data.close();
}

on loading I think you must check if its end of file

int main () {
  string line;
  ifstream myfile ("funds.txt");
  if (myfile.is_open())
  {
/*    while (! myfile.eof() )
    {
      getline (myfile,line);
      cout << line << endl;
    }*/
     getline(myfilen fundName);
     getline(myfile, numberOfShares);
     getline(myfile, purchasePrice);
     getline(myfile, currentValue);
    myfile.close();
  }

  else cout << "Unable to open file"; 

  return 0;
}

unless its just a single line...

I think something is wrong about your

  ifstream myfile ("funds.txt");
  if (myfile.is_open()) {
     myfile << fundName;
     myfile << numberOfShares ;
     myfile << purchasePrice ;
     myfile << currentValue;
     myfile.close();
  }

  else cout << "Unable to open file"; 

  return 0;

and i think data.open() and data.close() should be visible at the same code block
