I am trying to enhance my programming skills. Can someone help me out in letting me know the most important container classes i should be equipped with via c++ .?

  • Get yourself a [book](https://stackoverflow.com/q/388242/241631) and start from there instead of silly errands like trying to figure out knowing what container will make you successful. – Praetorian Oct 19 '15 at 02:19

Here is entire page devoted to c++ containers: http://www.cplusplus.com/reference/stl/. Many of those you won't start off using however, but for beginners I would say arrays, vectors, and maps. Which container to use comes down to how you want to store the data you have.

  • `array` is pretty much only a performance optimisation over the dynamic allocation done by `vector`, so I'd leave it off the must-learn-first list. `map` for sure. `list` makes sense conceptually - different performance compromises, but it's not needed all that frequently in most problem domains I've worked in. `unordered_map` is functionally close enough to `map` that it can be ignored initially. So - I agree with your list except for `array`, for whatever that's worth.... O_o. – Tony Delroy Oct 19 '15 at 01:45
