std::chrono::operator==(std::chrono::year_month_weekday)

定义于头文件 <chrono>
constexpr bool operator==(const std::chrono::year_month_weekday& x,
                          const std::chrono::year_month_weekday& y) noexcept;
(C++20 起)

比较二个 year_month_weekdayxy

!= 运算符从 operator== 合成

返回值

x.year() == y.year() && x.month() == y.month() && x.weekday_indexed() == y.weekday_indexed()

示例

#include <iostream>
#include <chrono>
using namespace std::chrono;
 
int main()
{
    constexpr auto ymwdi1 {Wednesday[1]/January/2021};
    constexpr year_month_weekday ymwdi2 {year(2021), month(1), weekday(3)[1]};
    std::cout << std::boolalpha << (ymwdi1 == ymwdi2) << '\n';
}

输出:

true
