What are the standard container types in C++?

In C++, the standard container types include vectors, lists, deques, sets, maps, and arrays. Each serves different purposes.

Can you explain the differences between a vector and a list?

Sure! A vector is a dynamic array that allows random access and is efficient for adding/removing elements at the end. A list, on the other hand, is a doubly linked list that allows efficient insertions and deletions from anywhere but does not support random access.

When should I use a map instead of a vector?

Use a map when you need to associate keys with values and require fast lookups. Vectors are better for ordered collections where you access elements by index.

What about performance differences between these containers?

Performance varies: vectors are fast for access and appending, lists are better for insertions/deletions, and maps have logarithmic time complexity for lookups.
