C++ Set
A set stores unique elements where they:
- Are sorted automatically in ascending order.
- Are unique, meaning equal or duplicate values are ignored.
- Can be added or removed, but the value of an existing element cannot be changed.
- Cannot be accessed by index numbers, because the order is based on sorting and not indexing.
To use a set, you have to include the <set> header file:
// Include the set library #include <set>
