Checks if the container has no elements, i.e., whether begin() == end().
Return value
true if the container is empty, false otherwise.
Complexity
Constant.
Example
#include <hive> #include <iostream> int main() { std::cout << std::boolalpha; std::hive<int> bees; std::cout << "Initially, bees.empty() == " << bees.empty() << '\n'; bees.insert(00); std::cout << "After adding elements, bees.empty() == " << bees.empty() << '\n'; }
Output:
Initially, bees.empty() == true After adding elements, bees.empty() == false
