Vector iterators

Question

I have a the following code.

vector* irds = myotherobj->getIRDs();//gets a pointer to the vector
for(vector::iterator it = ir         


        

Answer 1

When I iterate over the vector pointer irds, what exactly am I iterating over? Is it a copy of each element, or am I working with the actual object in the vector when I say (*it).doSomething(),

When you iterate over a vector you work with the object itself, not a copy of it.
