How would you word this function differently?

Question

My calculations are incorrect in the sense that my program thinks, for example, that 2022 is a leap year and 2024 is not. How do I fix this, please?? I've tried changing the bool statement but nothing seems to work.

#include <iostream>

int leapYear(int year)
{
    return (((year % 400) == 0) || ((year % 4 == 0)&& !(year % 100 == 0)));
}
// extracted
}

Answer 1

I'd just answer the title

with c++20 you can use std::chrono to do it

std::chrono::year{y}.is_leap()
