Define overload #1
template<class OutputIterator, class Size, class T> constexpr OutputIterator fill_n(OutputIterator first, Size n, const T& value);
Присваивает значение "value" каждому элементу в диапазоне [first, first + n].
Example, possible implementation
Define overload #2
template<class ExecutionPolicy, class ForwardIterator, class Size, class T> ForwardIterator fill_n(ExecutionPolicy&& exec, ForwardIterator first, Size n, const T& value);
TODO
Example, possible implementation
Examples
Example 1:
#include <iostream>
#include <algorithm>
#include <vector>
int main()
{
std::vector<int> v(10);
std::fill_n(std::begin(v), v.size(), 42);
for (auto it : v) {
std::cout << it << std::endl;
}
return 0;
