going back to the top line in input file

[mahurshi]

i am reading a file like this

ifstream infile(somefilenamestring.c_str())

while (infile >> myvariable)
{
/* do some interesting stuff */
}

now... if i want to get back to the first line of the file after i
executed this loop, what should i do ? is there a special thing that
needs to be done?

You could use seekg.

You could use seekg.

Don't forget to call clear() before seekg().
