I have generated a csv file with 27 columns.
third column is of time and i want to sort all the data according to this column in ascending order.
so can you please tell me how to do this.?
i have no clue where i should start.
i am fetching 18 columns from original csv file(say a1) using fscanf() and then calculating some variables and inserting it to another file(say a2) using fprintf();
the a2 file need to be sorted according to its third column.
