ifstream

[vw_bora]

Hi

I am using ifstream to read the contents of a file using getline(). I
would like to determine the line number of the file that the getline()
is reading. However, lookinfg at the istream API

http://www.cplusplus.com/reference/iostream/ifstream/

I can't see how it's possible to get the line number.
Anybody have a suggestion that I can use ?

Thank you.

You'll have to keep track of the line number yourself. One way to do
this is with a wrapper class for ifstream.

In that case you are not using C. C++ and C are different languages, if
you are using C++ I suggest asking in comp.lang.c++ where you will find
C++ programmers.

You're right - the API doesn't provide it. You need to read the file
from the beginning and keep track of the line number yourself.

Come on, let's have your self-righetous spiel about
how brilliant and considerate you are for responding
to the off-topic post, and about how the other
respondants are pedantic, mentally ill, and should be sued..
