[edit] Return value
Iterator to an element with key equivalent to key
. If no such element is found, past-the-end (see end()) iterator is returned.
[edit] Complexity
Constant on average, worst case linear in the size of the container.
[edit] Example
Run this code
#include <iostream> #include <unordered_set> int main() { std::unordered_multiset<int> example = {1, 2, 3, 4}; auto search = example.find(2); if(search != example.end()) { std::cout << "Found " << (*search) << '\n'; } else { std::cout << "Not found\n"; } }
Output:
Found 2
