reading stored float data from external external file in VC++?

I have float data from an external file in this format:
0.1 0.4 0.6
0.3 0.5 0.7
0.2 0.9 0.3

The columns represent 'j' array and the rows represents the 'i' array.
I am using check boxes as my inputs in the form of varying combinations, where each combination represents a particular set of rows from the external float data.

e.g if my input combination is:
//go to select the first two rows from the file();
//go to select the first and third rows from the file();

could some one help me on how to implemant the function that searches or selects the corresponding rows representing the input combinations?

currently i am using a longer method, by reproducing the corresponding rows whenever a corresponding combination is satisfied.
need a shorter method

Without using arrays of some kind with the check boxes, I can’t see who you can do it other you are now. If you had an array of check boxes, you can do something like:

for(i = 0; i< CheckBoxCount; i++)
    //get the row i
my suggestion would be to make a list of all rows you want to grab in the file(sorted would be best). then do a for loop until the end of file. and each time you come to a line in your list grab it.
here is the psudo code for this operation

make a list of lines to grab
sort list
for index = 0 to eof
   if line is in list
      advanc to next item in list
      grab line form file
do stuff with info from file
