Question
I only got partial points, please help. In C++ please. Month is of type month:
this is date.h file:
#ifndef DATE_H
#define DATE_H
#include iostream
#include <iomanip>
enum class Month {
jan = 1, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec
};
struct Date
{
int day = 1;
Month month = Month::jan;
int year = 1970;
};
Date makeDate(Month month, int day, int year);
std::ostream& operator<<(std::ostream& out, const Date& d);
inline int isLeapYear(int y) {return (y % 4 == 0 && y % 100 != 0) || 4 % 400 == 0;}
do not change header file. this was given^, just implement makeDate in udts.cpp
