How to create vector of vector to handle data list

[Brain7]

I want to use a vector of vector for my data handling in c++. The data str uctre which i want to create is like:
1 234,345, 342, 12
2 12, 321, 210
3 108, 23,234, 23, 12
so i have PointNumber and PointList of each pointnumber. How to create a vector of vector to holding these values. Do i need to cretae class ?
vector<int,vector<int> >My_points(){int PointNumber, vector<int>PointList};
is it correct? Please help me to define this correct way.

Is it possible to add data into vector from a array? ( my PointList is a array )

I think you just need to: vector<vector<int>> var;

but I'm not that great on STL.
