If I use reserve() to reserve enough elements for a vector, will push_back() (or insert()) throw any exceptions?
Is there a reference somewhere that specifies which stl function throw / not throw any exceptions?
Thank you.

It won’t need to perform a reallocation, and so the vector itself won’t throw any exceptions. The elements you’re inserting might throw exceptions when being copied into the vector, though, so
push_backandinsertcan still throw exceptions.Yes, the C++ standard contains that information.
