Read File Into Array

[Orca239]

I'm trying to read a file with 3 rows and 30 columns of chars into a two-dimensional array. I'm not really sure how that would work... could someone give me an idea of how to do it, or an example? Thanks.

This is something I wrote up really quick. Here is the text file I wrote up really quick to test run it:

a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd 
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 
31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60

And here is the code:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
    string str[30][3];
    ifstream myfile("testfile.txt");
    int a = 0;
    int b = 0;
    if(!myfile) //Always test the file open.
    {
                cout<<"Error opening output file"<<endl;
                system("pause");
                return -1;
    }
    while(!myfile.eof())
    {
      getline(myfile,str[a][b],' ');
      if(a ==29)
      {
           a=0;
           ++b;
           getline(myfile,str[a][b],' ');
      }
      a++;
    }
    system("pause");
}

Please note that I'm assuming that there are spaces in between each column, no spaces within a column, and one at the end of the last column. Things may need to be re-organized a bit if that is not the case. If you have any questions, just post back.

Alright thanks, that was helpful. =)
