C++ friend operator overloading cin>> - c++

Question

I am replacing a Read in function with a friend operator. I am having trouble referencing the friend operator in a void function. I am receiving and error "No member named 'Read' in Date" in the void GetDates function. Does anyone know how to fix this? Thank you!
Question 2:
I am now using cout<< operator but I am receiving errors for my variables: "'mn' is a private member of 'Date'"
class Date {
private:
int mn; //month component of a date
int dy; //day component of a date
int yr; //year comonent of a date
public:
//constructors
Date() : mn(0), dy(0), yr(0)
{}
Date(int m, int d, int y) : mn(m), dy(d), yr(y)
{}
//input/output functions
friend istream& operator>>(istream& Read, Date& d); //overload friend Read
friend ostream& operator<<(istream& write, Date& d); //overload friend write
void GetDates();
void Sort();
};
//Date class member functions
istream& operator >>(istream& Read, Date& d) //**NEED TO REPLACE with overload vs as friends to Date function**
{
char skip_char;
Read >> d.mn >> skip_char >> d.dy >> skip_char >> d.yr;
return Read;
}
void GetDates(Date l[], int &n) //reads list l, and returns count in n
{
cout << "How many date values are to be processed (1 - 100)? ";
cin >> n;
while ((n < 0) || (n > 100)) {
cout << "Invalid value; enter number between 0 and 100: ";
cin >> n;
}
for (int i = 0; i < n; i++) {
cout << "Enter a date (mm/dd/yyyy): ";
l[i].Read(); //ERROR HERE
}
}
ostream& operator <<(ostream& write, Date& d) //friend write
{
if (d.mn < 10)
cout << '0';
cout << d.mn << '/';
if (d.dy < 10)
cout << '0';
cout << d.dy << '/';
if (d.yr < 1000)
cout << '0';
if (d.yr < 100)
cout << '0';
if (d.yr < 10)
cout << '0';
cout << d.yr;
return write;
}

Answer 1

Read is the name of the stream that you are extracting from. An example of a stream that you can read from is cin. You need to replace this line:
l[i].Read(); //ERROR HERE
with
cin >> l[i];
Inside operator>> the cin object is now called Read.
The issue with your operator<< is that it needs to be declared as a friend, the same way you've done with operator>>.
Also, you are writing to cout instead of writing to write. This will not work, as soon as you try to writing to any other stream.
