Trouble with phone number class

[Kayoss]

This program is taken straight from the Deitel book, figure 8.3. But I can't seem to get it to compile:

#include <iostream>
#include <iomanip>

using namespace std;

class PhoneNumber {
   friend ostream &operator<<( ostream&, const PhoneNumber & );
   friend istream &operator>>( istream&, PhoneNumber & );

private:
   char areaCode{ 4 }; // 3-digit area code and null
   char exchange{ 4 }; // 3-digit exchange and null
   char line{ 5 };  // 4-digit line and null

}; // end class PhoneNumber

ostream &operator<<( ostream &output, const PhoneNumber &num )
{
   output << "(" << num.areaCode << ")" << num. exchange << "-" << num.line;

   return output; // enables cout << a << b << c;
} // end function operator<<

istream &operator>>( istream &input, PhoneNumber &num )
{
   input.ignore();
   input >> setw( 4 ) >> num.areaCode;
   input.ignore( 2 ); // skip ( and space
   input >> setw( 4 ) >> num.exchange;
   input.ignore();
   input >> setw( 5 ) >> num.line;  // input line

   return input;
}

int main()
{
   PhoneNumber phone; // create object phone

   cout << "Enter phone number in the form (123) 456-7890:\n";

   cin >> phone;

   cout << "The phone number entered was: ";

   cout << phone << endl;

   return 0;
} // end main

I get several errors, including "invalid member function declaration"s and "class PhoneNumber has no member named 'areaCode'". I had some compiler issues earlier with a program that worked fine for others, so I'm wondering if this is related or not.

Did you type it correctly? Are you sure the braces you typed for the member variables aren't square brackets? Did the error have a line number? Did you look closely at that line to see if you could spot the error?

Ah yes, I had curly braces instead of square brackets. My eyes must be going; thank you very much.
