Returning to beginning of file after getline

Question

So i\'ve read all the lines from a file thusly

while (getline(ifile,line))
    {
        // logic
    }

Where ifile is an ifstream and line

Answer 1

This is because the eof flag has been set on the stream - due to you reaching the end of the file. so you have to clear this as an additional step.

Eg

ifile.clear();
ifile.seekg (0, ios::beg);
