File I/O and Strings

Hello,

I usually don't like to post on this forum because I would rather read a book or try and work it out myself, but for some reason I am just completely stuck on this.

What I am trying to do, is load a text file from start to finish loading each line into a vector of strings.

For example, if the file contained:

hello
this
is
a
forum

Then a vector of strings
vector <string>
0 would be hello
1 would be this
2 would be is
3 would be a
4 would be forum

I have been trying to do this with the fstream.h header file, but I am just continually getting errors, or compile problems.



I would post code, but I have attempted it so many times I wouldn't know which one to paste. I am looking for an example now.

Thanks for any help, and please keep the flames to a minimum.

Something like -

Code:

---

#include <iostream>
#include <fstream>
#include <vector>
#include <algorithm>
#include <string>

using namespace std;

int main()
{
        //Assumes text file is in program dir
        ifstream i("t.txt");

        vector<string> s;

        copy(istream_iterator<string>(i),istream_iterator<string>(),back_inserter(s));

        copy(s.begin(),s.end(),ostream_iterator<string>(cout,"\n"));

        return 0;

}

---

Code:

---

#include <fstream>
#include <string>
#include <vector>

using namespace std;

int main()
{
 vector<string> TheLines;

 string currentLine;

 fstream input ("input.txt");
 while( ! input.eof() )
 {
  getline(input,currentLine);
  TheLines.push_back(currentLine);  //add the current line to the end of the vector
 }

 input.close();
 return(0);
}

---

That is another way of doing it with out using the algorithim header file, which is sometimes easier to under stand for beginners
