Modern C++ Programming Cookbook

Getting ready

The algorithms for set operations work with iterators, which means they can be used for standard containers, C-like arrays, or any custom type representing a sequence that has input iterators available. All the examples in this recipe will use std::vector.

For all the examples in the next section, we will use the following ranges:

    std::vector<int> v1{ 1, 2, 3, 4, 4, 5 };    std::vector<int> v2{ 2, 3, 3, 4, 6, 8 };    std::vector<int> v3;
