Initialize array of vectors

I am trying to initialize an array of vectors. How can I do that ?

The following code is wrong:

vector<int> A[] = vector<int>()[10];

std::array<std::vector<int>, 10>

This will gives you an array of 10 with vectors in it.

Try just

vector<int> A[10];

It will default-initialize all ten vector objects.
