WebThe reason is simply that the += operator is not defined for the Bidirectional iterator you are using.. For all iterators there is at least: Copy-assignable and destructible, i.e. X b(a); and b = a; Can be incremented, i.e. ++a and a++ Everything else depends on the type of iterator check the table here:. As you see a random-access iterator would do the trick.
