I'm no guru on streams so won't give you an elegant answer. But to just
make your code 'work' you could try using nested blocks to 'refresh' fin
each time you use it, thus:
int main()
{
{
ifstream fin("text.txt");
doStuff(fin);
}
{
ifstream fin("text2.txt"); // or s/text2/text
doStuff(fin); // or s/Stuff/OtherStuff
}
}
On second thought, the approach actually has a certain elegance
because now you're treating each file EXACTLY the same. It can also
solve your second problem (see comments).
Hope that helps,
