C++ set is an inbuilt associative container that contains unique objects because the value of the elements identifies the container. They store unique elements in a particular order. The value of the elements in a set cannot be modified once they are put into the container, but other operations such as removal and insertion on the container can take place.

C++ Set Example

C++ set containers are slower than the unordered_sets containers when it comes to accessing individual elements by their key, but the main advantage with sets is that they allow the direct iteration on the subsets based on their order of items in the container.

The application of sets is mainly in binary search trees.

In the sets, we access elements with the help of key which is identified.
