std::chrono::operator==,(std::chrono::month_day)(3) | C++ Standard Libary | std::chrono::operator==,(std::chrono::month_day)(3) |
NAME¶
std::chrono::operator==,(std::chrono::month_day) - std::chrono::operator==,(std::chrono::month_day)
Synopsis¶
Defined in header <chrono>
constexpr bool operator==( const std::chrono::month_day& x,
const std::chrono::month_day& y ) (1) (since C++20)
noexcept;
constexpr std::strong_ordering operator<=>( const
std::chrono::month_day& x, (2) (since C++20)
const
std::chrono::month_day& y ) noexcept;
Compares two month_day values.
The <, <=, >, >=, and != operators are synthesized from
operator<=> and operator==
respectively.
Return value¶
1) x.month() == y.month() && x.day() == y.day()
2) x.month() <=> y.month() != 0 ? x.month() <=> y.month() :
x.day() <=> y.day()
Example¶
// Run this code
#include <chrono>
#include <iostream>
int main()
{
constexpr auto md1{std::chrono::August/15};
constexpr auto md2{std::chrono::month(8)/std::chrono::day(15)};
std::cout << std::boolalpha << (md1 == md2) << '\n';
static_assert(md1 <= md2);
}
Output:¶
true
