Creating a new C++ subvector?

Question

Say I have a vector with values [1,2,3,4,5,6,7,8,9,10]. I want to create a new vector that refers to, for example, [5,6,7,8]. I imagine this is just a matter of creating a v

Answer 1

You don't have to use push_back if you don't want to, you can use std::copy:

std::vector subvector;
copy ( v1.begin() + 4, v1.begin() + 8, std::back_inserter(subvector) );
