非成员函数

operator==

operator<<

辅助类

formatter<std::chrono::year_month_weekday_last>

 

在标头 <chrono> 定义
constexpr bool operator==(const std::chrono::year_month_weekday_last& x,                           const std::chrono::year_month_weekday_last& y) noexcept;		(C++20 起)

比较二个 year_month_weekday_last 值 x 与 y 。

!= 运算符从 operator== 合成。

返回值

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

示例

运行此代码

#include <iostream>
#include <chrono>
using namespace std::chrono;
 
int main()
{
    constexpr auto ymwdl1 {Tuesday[last]/11/2021};
    auto ymwdl2 = Tuesday[last]/11/2020;
    ymwdl2 += months(12);
    std::cout << std::boolalpha << (ymwdl1 == ymwdl2) << '\n';
}

输出：

true
