manual in Linux: $ man 3 std::set<Key,Compare,Allocator>::begin,std::set<Key,Compare,Allocator>::cbegin
NAME
std::set<Key,Compare,Allocator>::begin,std::set<Key,Compare,Allocator>::cbegin - std::set<Key,Compare,Allocator>::begin,std::set<Key,Compare,Allocator>::cbegin
Synopsis
iterator begin(); (until C++11)
iterator begin() noexcept; (since C++11)
const_iterator begin() const; (until C++11)
const_iterator begin() const noexcept; (since C++11)
const_iterator cbegin() const noexcept; (since C++11)
Returns an iterator to the first element of the container.
If the container is empty, the returned iterator will be equal to end().
range-begin-end.svg
Parameters
(none)
Return value
Iterator to the first element
Complexity
Constant
Notes
Because both iterator and const_iterator are constant iterators (and may in fact be the same type), it is not possible to mutate the elements of the container through an iterator returned by any of these member functions.
Example
// Run this code
#include <set>
#include <iostream>
int main() {
std::set<int> set = { 6, 1, 3, 4, 2, 5 };
for (auto it = set.begin(); it != set.end(); ++it)
std::cout << *it << "\n";
}
Possible output:
1
2
3
4
5
6
