Is there a C++ iterator that can iterate over a file line by line?

Question

I would like to get an istream_iterator-style iterator that returns each line of the file as a string rather than each word. Is this possible?

Answer 1

Here is a solution. The exemple print the input file with @@ at the end of each line.

#include 
#include 
#include 
#include 

using namespace std;

class line : public string {};

std::istream &operator>>(std::istream &is, line &l)
{
    std::getline(is, l);
    return is;
}

int main()
{
    std::ifstream inputFile("input.txt");

    istream_iterator begin(inputFile);
    istream_iterator end;

    for(istream_iterator it = begin; it != end; ++it)
    {
        cout << *it << "@@\n";
    }

    getchar();
}

Edit : Manuel has been faster.
