      std::chrono::operator==,<=>(std::chrono::day)

      From cppreference.com
      <cpp‎ |chrono‎ |day
       
       
      Date and time library
       
       
      Defined in header<chrono>
      constexprbool operator==(conststd::chrono::day& x,
                                 conststd::chrono::day& y)noexcept;
      (1)(since C++20)
      constexprstd::strong_ordering operator<=>(conststd::chrono::day& x,
                                                 conststd::chrono::day& y)noexcept;
      (2)(since C++20)

      Compare the twostd::chrono::dayx andy.

      The<,<=,>,>=, and!= operators aresynthesized fromoperator<=> andoperator== respectively.

      [edit]Return value

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

      [edit]Example

      Run this code
      #include <chrono>#include <iostream> int main(){constexprstd::chrono::day x{13}, y{31};    static_assert(x!= y); ifconstexpr(constexprauto res= x<=> y; res<0)std::cout<<"x is less than y\n";elseifconstexpr(res>0)std::cout<<"x is greater than y\n";elsestd::cout<<"x and y are equal\n"; usingnamespace std::literals::chrono_literals;     static_assert((6d< 9d)&&(6d== 6d)&&(6d<= 9d)&&(9d> 6d)&&(9d!= 6d)&&(9d>= 6d));}

      Output:

      x is less than y
