Is std::vector copying the objects with a push_back?

Question

After a lot of investigations with valgrind, I\'ve made the conclusion that std::vector makes a copy of an object you want to push_back.

Is that really true ? A vect

Answer 1

Not only does std::vector make a copy of whatever you're pushing back, but the definition of the collection states that it will do so, and that you may not use objects without the correct copy semantics within a vector. So, for example, you do not use auto_ptr in a vector.
