< cpp | chrono | year month
constexpr bool operator==( const std::chrono::year_month& x, const std::chrono::year_month& y ) noexcept; |
(1) | (since C++20) |
constexpr std::strong_ordering operator<=>( const std::chrono::year_month& x, const std::chrono::year_month& y ) noexcept; |
(2) | (since C++20) |
Compares the two year_month
objects x
and y
.
Return value
1) x.year() == y.year() && x.month() == y.month()
2) x.year() <=> y.year() != 0 ? x.year() <=> y.year() : x.month() <=> y.month()
Example
Run this code
#include <iostream> #include <chrono> int main() { std::cout << std::boolalpha; constexpr std::chrono::year_month ym1 {std::chrono::year(2021), std::chrono::month(7)}; constexpr std::chrono::year_month ym2 {std::chrono::year(2021)/7}; std::cout << (ym1 == ym2) << '\n'; }
Output:
true
