how to put data from text files to a pair?

The text file I am using has the following text:

3   4
5   6

And the output should come 2. It should count pairs.

while (getline(ifs, line)) {
        istringstream is(line);
        pair<int, int> p;
        ifs >> p.first;
        ifs >> p.second;
        cout << p.first << "  " << p.second<< endl;

        set<pair<int, int> > set1;
        }

it should be is >> p.first; and is >> p.second; you must read from stringstream(is) instead of the filestream(ifs)

Also just a sidenote, stop using ifs, line, p, etc and give them meaningful names. This not only aids YOU while programming, but also minimizes bugs, improves readability and makes you think in the right direction.
