When should I use sets in C++?

When should I use sets in C++?

You should use sets in C++ when you need a collection of unique elements and want to perform operations like union, intersection, or difference.

What are the advantages of using sets over vectors?

Sets automatically handle duplicates and provide faster search times due to their underlying data structure, typically a balanced tree.

Can I store custom objects in a set?

Yes, you can store custom objects in a set, but you need to define a comparison operator for the objects to ensure uniqueness.

Are there any performance considerations I should be aware of?

Yes, while sets offer fast lookups, insertions and deletions can be slower than vectors due to the need to maintain order and uniqueness.
