How read/write them into arrays

Hello, all: The following is a part of an initial market data:

20090319,A,14.6,14.93,14.45,14.74,27928
20090320,A,14.75,14.95,14.29,14.43,42467
20090323,A,15,15.89,15,15.89,46303
20090324,A,15.66,16.055,15.63,15.79,27188
20090325,A,16.02,16.43,15.5401,15.96,29293
20090326,A,16.05,17.18,15.81,17.14,59793
20090327,A,16.79,16.96,16.21,16.21,32163
20090330,A,15.82,15.86,15.14,15.39,39704
20090331,A,15.52,15.7,15.27,15.37,47358
20090401,A,15.12,16.13,15.02,16,39561
20090402,A,16.39,16.77,16.18,16.32,42830
20090403,A,15.7,16.6,15.7,16.46,28789
20090406,A,16.31,16.32,15.74,15.98,33559
20090407,A,15.67,15.74,15.39,15.6,35614

It consists of 7-column, the columns are separated by comma ','.

Now I want to read/write the 1st, 2nd and 6th columns into different arrays
data[], Name[] and close[], which C++ language sentence can do this job.

if you know c++ use a class or a structure eg 'marketdata' with attributes, data, name, and close

then declare an array of objects of this class

marketdata records[10];

then you can put it in a loop and read the info into the structure like records[i].close =....

The initial file is marketdate.txt, 1st column is date, 2nd Name, 3-6 columnsare prices. My purpose is to read date, name and 6th's price into array date[365], name[ ] and close[365].

I guess the meaning of your answer may like:

class  marketdata
{
  public:
            string  date;
            string  name;
            float    close;
};

int  main( )
 {
    marketdata data_array[ 7][365];
  …(to read marketdate.txt, how?)…..
          ………………………………
 }

Now the question is how to read the related data in the marketdat.txt
into the array?

What's wrong with >>?
