std::chrono::weekday_last

成员函数

weekday_last::weekday_last

weekday_last::weekday

weekday_last::ok

非成员函数

operator==

operator<<

辅助类

formatter<std::chrono::weekday_last>

 

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

比较二个 weekday_last 值 x 与 y 。

!= 运算符从 operator== 合成。

返回值

x.weekday() == y.weekday()

示例

运行此代码

#include <iostream>
#include <chrono>
 
int main()
{
    constexpr auto wdl1 {std::chrono::Tuesday[std::chrono::last]};
    constexpr std::chrono::weekday_last wdl2 {std::chrono::weekday(2)};
    std::cout << std::boolalpha
              << (wdl1 == wdl2) << ' '
              << (wdl1 == std::chrono::Wednesday[std::chrono::last]) << '\n';
}

输出：

true false
