NAME¶

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

Synopsis¶

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

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

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

Return value¶

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

Example¶

// Run this code

#include <iostream>
#include <chrono>

int main()
{
std::chrono::day d1{15};
std::chrono::day d2{20};

d1 == d2 ? std::cout << "d1 and d2 are equal\n"
: std::cout << "d1 and d2 are not equal\n";

using namespace std::literals::chrono_literals;

std::cout << std::boolalpha
<< (6d < 9d) << ' ' << (6d == 6d) << ' ' << (6d <= 9d) << ' '
<< (9d > 6d) << ' ' << (9d != 6d) << ' ' << (9d >= 6d) << '\n';
}

Output:¶

d1 and d2 are not equal
true true true true true true
