Hello all u guys out there
"you"

Ive got a problem Undrestanding in example what it means
missing apostrophe, uppercase U, "understanding"

class point
{
...
}
missing semicolon

point &function1()
{
point sample;
return sample;
}
for a newbie this function constitutes an error

whats meaning of & in a function??

missing apostrophe, extranous question mark

the meaning of "&" depends on the context; consult your nearest C++
textbook.

Actually our bonfire night, in Norway, is tonight, 23/24th of June,
midsummer's night!

One bonfire got a little out of hand this year (it was probably
calculated using C instead of C++): <url:

the left in the upper photo is probably the one who sat on top.

i'm not good in english...
then accept my Apologize

in example in file below if you clean & before operator you got an
error
why it couldn't answer when we erase & ?

//phonenumber.h

#ifndef PHONENUMBER_H
#define PHONENUMBER_H

#include <iostream>
using std::ostream;
using std::istream;

#include <string>
using std::string;

class PhoneNumber
{
friend ostream &operator<<( ostream &, const PhoneNumber & );
friend istream &operator>>( istream &, PhoneNumber & );
private:
string areaCode; // 3-digit area code
string exchange; // 3-digit exchange
string line; // 4-digit line
}; // end class PhoneNumber

#endif

----------------
//PhoneNumber.cpp

#include <iomanip>
using std::setw;

#include "PhoneNumber.h"

// overloaded stream insertion operator; cannot be
// a member function if we would like to invoke it with
// cout << somePhoneNumber;
ostream &operator<<( ostream &output, const PhoneNumber &number )
{
output << "(" << number.areaCode << ") "
<< number.exchange << "-" << number.line;
return output; // enables cout << a << b << c;
} // end function operator<<

// overloaded stream extraction operator; cannot be
// a member function if we would like to invoke it with
// cin >> somePhoneNumber;
istream &operator>>( istream &input, PhoneNumber &number )
{
input.ignore(); // skip (
input >> setw( 3 ) >> number.areaCode; // input area code
input.ignore( 2 ); // skip ) and space
input >> setw( 3 ) >> number.exchange; // input exchange
input.ignore(); // skip dash (-)
input >> setw( 4 ) >> number.line; // input line
return input; // enables cin >> a >> b >> c;
} // end function operator>>
