  hi!
  i'm beginner in c++ and i am trying to read an ASCII file:
  the file has the following structure:
  

  
        0        17  
  10.125  -85.189      
  10.115  -85.181      
  10.106  -85.171      
   10.1  -85.158      
   10.1  -85.151      
  10.097  -85.138  
  ......
  

  
  how can i read this file into a matrix with 2 columns and "n"rows?
  thanks!

  Code:

  #include <fstream>
  using std::ifstream;
  using std:fstream;
  

  
  

  include <iostream>

  
  using std::cout;
  using std::cin;
  using std::ios;
  

  
  void main()
  {
    float List[100][2];
    int x = 0;
  

  
    ifstream inFile("InputFile.txt", ios::in);   // Input File Stream
  

  
    // Loop until end of file
    while (inFile.eof() == false)
    {
       cin >> List[x][0] >> List[x][1];   // Input the first and second columns into row x
       x++;   // Increment your counter
    }
  

  
    // Close file
    inVideoFile.close();
  }

  
  

  
  That should work.  If you have any problems, just respond and I'll try to be prompt with my reply.  Good luck!
