Step 5 of 5
operator< and sorting
std::sort (from <algorithm>) orders anything that has a <. Define operator< and your own type becomes sortable:
std::vector<Player> team = ...;
std::sort(team.begin(), team.end());
(Vectors are the next module; for now just know team.begin(), team.end() means "the whole vector".)
Your turn: define operator< for Player so sorting puts the most kills first, and for equal kills, the name alphabetically first.
