I have a class Bar:

class Bar
{
public:
Bar(void);
~Bar(void);
};

And a class Foo that gets a reference to Bar object as a constructor parameter and needs to save it in a private member bar_ :

class Foo
{
private:

Bar& bar_;
public:
Foo(Bar& bar) : bar_(bar) {}
~Foo(void) {}
};

This doesn't compile :

overloaded member function not found in 'Parser'

missing type specifier - int assumed. Note: C++ does not support default-int

Now i suspect couple of things that i need to assure, the second error is for Bar& bar_; declaration in Foo. Do i need to use an explicit constructor when declaring bar_ ?

I am interested in learning how the compiler works regarding this matter, so a detailed explanation would be highly appreciated.

Thanks.
