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 <chrono>
#include <iostream>

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
