Thread: I/O Question

You read one line at a time. Use a counter if you want a specific number of lines to read.

Your question seems quite vague because the answer is too simple. How are you reading from the file?

if you know the length you can use

i would jsut read in one line at a time, possibly store each string
into a vector just incase im going to end up using all the
lines, and simply call the spot in the vector for the line i wanted

ex

Code:

vector<string> vS;
string S;
ifstream file("myfile.txt");
while(!file.fail())
{
      getline(file, S, '\n');
      vS.push_back(S);
}
file.close();
cout << vS[13] << endl; //for line 14 of the file

then again im kind of parcial to vectors, hense the name :/

of course these will require :

Code:

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

using namespace std;
