constexpr /*iterator*/ begin() const;		(seit C++20)

Ermittelt einen Iterator zum Anfangswert.

Rückgabewert

iterator {value_ }

Beispiel

Führen Sie diesen Code aus

#include <iostream>
#include <ranges>
 
int main()
{
    auto iota{std::views::iota(2, 6)};
    auto iter{iota.begin()};
    while (iter != iota.end())
        std::cout << *iter++ << ' ';
    std::cout << '\n';
}

Ausgabe
