push back multiple types of data in a vector in c++

let's say I have a vector full of points like this vector<Point3f> cluster_points. Now I am getting distance between 2 points for each point in the vector. Now I want to store all these data in a container like below.
{distance, (both point's index number from cluster_points)}
e.g.
{70.54, (0,1)}; {98.485, (1,2)}; {87.565, (2,3)}; {107.54, (3.4)};

How can I do this in c++11?
