std::hive<T,Allocator>::begin, std::hive<T,Allocator>::cbegin
iterator begin() noexcept; | (1) | (since C++26) |
const_iterator begin() const noexcept; | (2) | (since C++26) |
const_iterator cbegin() const noexcept; | (3) | (since C++26) |
Returns an iterator to the first element of the hive.
If the hive is empty, the returned iterator will be equal to end().
Return value
Iterator to the first element.
Complexity
Constant.
Example
#include <hive>
#include <print>
int main()
{
std::hive h{"bee", "wasp", "hornet"};
while (h.cbegin() != h.cend())
{
std::println("{}", *h.cbegin());
h.erase(h.begin());
}
}
Output:
bee wasp hornet
