Working with ascii data files

[vRltwE]

Hi,

I am working with ascii data files, in fact they are matrix stored in ascii data files.

Someone can recomend a tutorial or something like that?

Thanks

A tutorial for what?

I have a matrix (double values) stored in an ASCII data file

11.33 12.33 13.33
14.33 15.33 16.33
17.33 18.33 19.33

I think to use two for loops to load the values to a matrix in memory,..., some think like

vector matrix[cols][lines];
for(int i = 0; i < lines; i++) {
     for(int j = 0; j < cols; j++) {
          matrix[i][j] = iFile.get();
     }
}

There is some way I can load the complete matrix stored in file to a matrix in memory?
