How to write multiple .tsv files

[junhui.liao]

Hi, guys,

I have to read from a big txt file into multiple small .tsv files.
But I was blocked at the file name. Since according to the
definition of ofstream, the filename is constant char *, then
is no way to modify the filename, which results in unable to
write multiple files.

Does anybody has any idea on this ?

Thanks a lot in advance !

Best !

my code in C++, sorry for the missing.
If there is any solution based on ROOT,
it's good also.
