Question

How can I use std::shared_ptr for array of double? Additionally what are advantages/disadvantages of using shared_ptr.

Answer 1

You can also provide an array deleter:

template class ArrayDeleter {
public:
    void operator () (T* d) const
    { delete [] d; }
};

int main ()
{
    std::shared_ptr array (new double [256], ArrayDeleter ());
}
