Does pop_back() really invalidate *all* iterators on an std::vector?

Question

std::vector ints;

// ... fill ints with random values

for(std::vector::iterator it = ints.begin(); it != ints.end(); )
{
    if(*it < 10)
         


        

Answer 1

Iterators are only invalidated on reallocation of storage. Google is your friend: see footnote 5.

Your code is not working for other reasons.
