getting an array from an STL vector

[Digital Puer]

Hi, in Java I know that you can convert a vector into an array of
Object with toArray(). Is there a corresponding function in STL
that will immediately convert a vector of T into an array of T?

// v is the name of the vector, arr is the name of the array

std::copy(v.begin(), v.end(), arr);

Or (a bit more ugly) as mentioned on another thread you can take the
address of the first object and use it as a array (since a vector will
store the elements contiguously).

A std::vector internally has an array of T. To get it use e.g. &v[0].
This probably is in the FAQ.
