Differences between vector, set, and tuple

Question

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

Answer 1

A tuple is a heterogeneous collection of objects, which should be treated as a single unit: for example, ("John", "Smith", 30) is a (String, String, Integer) tuple.

A list (in C++: and also vector) is a homogeneous collection of objects -- that is, each object can be treated uniformly. Whether they are actually the same type depends on the language, but the point is that they can be processed the same way.

A set is an unordered unique homogenous collection -- you know what objects it contains, and what type they are, but not in what order, and it only contains one of each object.
