std::chrono::operator==,(std::chrono::year)(3) C++ Standard Libary std::chrono::operator==,(std::chrono::year)(3)

NAME

std::chrono::operator==,(std::chrono::year) - std::chrono::operator==,(std::chrono::year)

Synopsis


Defined in header <chrono>
constexpr bool operator==( const std::chrono::year& x, (1) (since C++20)
const std::chrono::year& y ) noexcept;
constexpr std::strong_ordering operator<=>( const
std::chrono::year& x, (2) (since C++20)
const std::chrono::year& y ) noexcept;


Compare the two std::chrono::year x and y.


The <, <=, >, >=, and != operators are synthesized from operator<=> and operator==
respectively.

Return value


1) int(x) == int(y)
2) int(x) <=> int(y)

Example

// Run this code


#include <iostream>
#include <chrono>


int main()
{
using namespace std::chrono;


constexpr year y1{2020};
constexpr year y2{2021};


std::cout << std::boolalpha << (y1 != y2) << '\n';


static_assert(
(2020y < 2023y) && (2020y == 2020y) && (2020y <= 2023y) &&
(2023y > 2020y) && (2023y != 2020y) && (2023y >= 2020y)
);
}

Output:


true
