In reply to Piotr Nycz. std::lexicographical_compare takes ( firstIter1 , firstIter2, secondIter1, secondIter2 ) as arguments.

In reply to Jonathan Boccara.

make `data_` an array? But not std::array – since it has `operator <` too. Like `size_t numElems; std::string data[MAX_DATA];` And show that it can be implemented something like array_view on them – like C++17 string_view: http://en.cppreference.com/w/cpp/string/basic_string_view

In reply to Piotr Nycz. Wow thanks for pointing this out Piotr. I didn't know about them and this is a very good point. I'll try to think of another use case for lexicographical_compare then. Actually, do you have any in mind?

To last example: well, you could find better subject than std::vector – because std::vector already has `operator <` implemented in the way as in your example: http://en.cppreference.com/w/cpp/container/vector/operator_cmp
