While this is not gcc-help, maybe we could make a FAQ item for this.
For people who want to do something like this, I suggest
std::vector<int> i(5, 23);
If the reason vector wasn't used in the first place was because some
API needs an array, then use
std::vector<int> vector_i(5, 23);
int* i = &*vector.begin();
The reason for the &* is to convert the vector iterator into a
pointer to the first element.
