  1. vector<\/code>: There are vectors in functional languages too, like this package<\/a><\/li>\n
  2. unordered_set<\/code> – Unordered\/ordered refers to the underlying implementation; how the elements are actually stored.<\/li>\n
  3. vector.cend<\/code> – cend<\/code> is a constant iterator pointing to the end. Constant iterators don’t let you modify the value pointed to by the iterator.<\/li>\n
  4. emplace<\/code> – Emplace is like insert except it creates the object “in-place”; you pass emplace the parameters you would pass to the object’s constructor.<\/li>\n
  5. push_back<\/code> – This is to maintain a uniform interface. Some containers like std::list let you push_front<\/li>\n
  6. Why does empty()<\/code> return a boolean? Shouldn’t it be isEmpty()<\/code>?: Should it? Says who? You’re used to Python\/Scala\/Haskell but that’s hardly the one true way.<\/li>\n
  7. Also, the .begin()<\/code> and .end()<\/code> seems inconsistent. begin()<\/code> is a verb while end()<\/code> is a noun in this context. begin denotes to start something whereas it simply returns a pointer to start. Shouldn’t the method be called either start<\/code> which is a noun and goes well with “end” or beginning<\/code> atleast instead of begin<\/code>: I suppose. This seems like a petty gripe. It’s just the way it is.<\/li>\n
  8. Why does list.unique<\/code> not return a set<\/code>? It seems weird it not only modifies the data structure (coming from a functional world, it seems really weird to mutate data as side effects) and it is doubly weird here since C++ already has sets. Am I understanding unique<\/code> wrong??: A lot of things will be weird if you carry that mindset of no side-effects into C++. The same open mind that let you learn Python\/Scala\/Haskell should be applied to C++ if you are serious about learning it. list.unique<\/code> is more like Ruby’s Array#uniq<\/code>. From the documentation<\/a>:<\/li>\n<\/ol>\n
    \n

    Notice that an element is only removed from the list container if it compares equal to the element immediately preceding it. Thus, this function is especially useful for sorted lists.<\/p>\n<\/blockquote>\n

    As described, returning a set would lose information because it wouldn’t preserve duplicates in the case where they are not consecutive.<\/p>\n

    Like I said, if you’re serious about learning C++ you’ll have to deal with some of these language\/library design decisions. Many of these points seem like petty gripes to me. Some of these are “just the way it is”. Some things in C++ are straight up crazy, but if you’re serious about C++ what are you going to do? Indeed, Haskell for example seems to have a more straightforward design that “naturally follows,” but that’s a different kind of language. Hopefully you can get over this.<\/p>\n<\/p><\/div>\n
