    T 7:07 This code works for me as long as I also #include <string>. Anyone know why the example here did not need it?

    Thank you for the clear and thorough explanations, it helped much more than what my "professor" was saying. Very abrupt ending though, seemed like you cut yourself off before finishing your thought.

    I think this tutorial is great! I only came across maps practicing firecode.io, but was never introduced to it in class yet. This helped a lot. Thanks so much!

    You should have used string as key and int as value for this example, What you did now could also just be done with a string array!

    at 6:07 you are saying that the first assignment is valid and no duplicates are allowed but when you accessed the value it gave the last assigned value..contradiction..pls clear.

    It is pointless to use integers as the key… you might as well just use a standard vector for that… use a map when you want to "name" your indexes.

    Huh? There's no point in hashing a map with integer values…. you might as well use a vector at that point.
