Differences between vector, set, and tuple

Question

What are the differences between vectors, sets, and tuples in programming?

Answer 1

Vectors have an ordering

Tuples are ordered and can have repeat elements.

Sets are unordered and repeat elements do not change the set.

For example: {a,b}, {b,a}, and {b,b,a} are all the same set, while (a,b), (b,a) and (b,b,a) are all different tuples.
