Hello there;
I am new to object oriented programming need to use vectors. basically I have data from CSV file and I stored it in a vector. I need to partition this vector to n vectors and I need it to be dynamic.
I started using class in order to create vector of dynamic objects ( ihope it is right) but I am confuse how can I use vector.

}every time I have to pass value from vector m1 to the add_member function to check whether this value will be store in the same vector or a new vector until I get n vector (cluster).
Many Thanks
