I want to debug my code, and there’s a vector especially that I want to see the content off, how can I make this happen?

I’m using Visual Studio.

Here’s my code:

    Eigen::VectorXf q_positions(n);

    // Retrieve positions into q_positions 
    for (int i = 0, d = 0; d < n; d += n) {
        q_positions.segment(i * 3, 3) = q.segment(d * 6, 3);
        i += 1;
    }
