actually I am trying to extract columns of a csv file . The problem I am facing is that the csv can have arbitrary number of columns , the number of columns will be defined by the user and will be given as an input to script
Now my question is how to define arrays when I don't know while coding , how many columns will be extracted i.e. if I want column 1 entries to go in one array , second column entry to another and so on . How can i define my array
