-The **`cbegin()`** method returns a constant iterator that points to the first element of an `std::unordered_set`. A constant iterator allows read-only access to elements and prevents modification. Because `unordered_set` does not maintain any defined order, the element returned by `cbegin()` depends on its internal hash table structure.
