Excellent Patrik! This works right out of the box when I add, "-std=c++11" to the compiler options ([Error] range-based-for loops not allow in C98 mode). Thanks you

EDIT: Note that even most of the variables have the same names!!! The biggest difference between the two programs seems to be that I work in a Unix style --where it's natural to read from standard input and write to standard output-- and he probably works on Windows.
Thanks Alvaro,
I had something close to this but abandoned the whole idea when I encountered a compiler error about range-based for loops. I got your's to work also with a little bit of changes.

I like to use a little helper class called "line", so that I can use iterators to read /write from std::cin/std::cout and also to read/write from the intermediate stringstream:
