std::chrono::weekday::operator[] - std::chrono::weekday::operator[]

Synopsis

constexpr std::chrono::weekday_indexed operator[](unsigned index) (1) (since C++20)
const noexcept;
constexpr std::chrono::weekday_last (2) (since C++20)
operator[](std::chrono::last_spec) const noexcept;

1) Constructs a weekday_indexed from *this and index. The result represents the
index-th weekday in some yet-to-be-specified month. If index is not in the range [0,
7] or if !ok() the values held in the result is unspecified.
2) Constructs a weekday_last from *this. The result represents the last weekday in
some yet-to-be-specified month.

Return value

1) std::chrono::weekday_indexed(*this, index)
2) std::chrono::weekday_last(*this)

Example

// Run this code

#include <chrono>
#include <iostream>
using namespace std::chrono;

int main()
{
constexpr auto second_tuesday_in_October_2019 =
year_month_day{ Tuesday[2] / October / 2019y };

constexpr auto last_tuesday_in_October_2019 =
year_month_day { Tuesday[last] / October / 2019y };

std::cout << second_tuesday_in_October_2019 << '\n'
<< last_tuesday_in_October_2019 << '\n';
}
