std::chrono::weekday_last::weekday_last
|
(since C++20) |
Constructs a weekday_last object storing the weekday wd.
Notes
A more convenient way to construct a weekday_last is with weekday's operator[], i.e., wd[std::chrono::last].
Example
#include <chrono>
#include <iostream>
using namespace std::chrono;
int main()
{
const year_month_day ymd{floor<days>(system_clock::now())};
const weekday_last wdl{Sunday[last]}; // A last Sunday of a month
const year_month_day last_sun{ymd.year() / ymd.month() / wdl};
std::cout << "The last Sunday of current month falls on "
<< (int)last_sun.year() << '/'
<< (unsigned)last_sun.month() << '/'
<< (unsigned)last_sun.day() << '\n';
}Possible output:
The last Sunday of current month falls on 2021/9/26© cppreference.com
