    sets and do operations on them

    I try to take the difference of two sets and record the rest into another set...
    but it is giving me errors
    Code:
    set<int> a,b,c;
    c = set_difference(a.begin(),a.end(),b.begin(),b.end(),c.begin());
    what should I do?

    That last parameter needs to be std::inserter(c, c.begin()) not c.begin()
