Given the program, which of the following class member accesses are legal?

```
#include using namespace std;class
DayOfYear{public: void input(); void output(); int
month; int day;};int main(){ DayOfYear birthDay;
birthDay.input(); // a) birthDay.day = 25;
// b)
cout << birthDay.month; // c)
cout << birthDay.output(); // d)
if(birthDay.month == 1) // e)
cout <<
```

All of them are legal. Everything is pubic now, so any function can access
any member
