Strange error in VS

[LaLaLaBaBaBaRaRaRa]

Hi guys,
this is my code:

class Date{
private:
	int day;
	int m;
	int y;

public:
	Date(int day,int m,int y){ //constructor
		this->day=day;
		this->m=m;
		this->y=y;
	}
	Date(Date time){ //copy constructor, ERROR
		this->day=time.day;
		this->m=time.m;
		this->y=time.y;
	}
};

and I get this error:
error C2652: 'Date' : illegal copy constructor: first parameter must not be a 'Date'.

Isn't the whole point of copy constructor is get it's own class parameter?

Thanks!

Try to change it to:

Date(const Date& time){ //copy constructor, ERROR
		this->day=time.day;
		this->m=time.m;
		this->y=time.y;
	}

Edit: 1st Line deleted.

According to the C++ STandard

Section 12.8 Copying and moving class objects

2 A non-template constructor for class X is a copy constructor if its first parameter is of type X&, const X&, volatile X& or const volatile X&, and either there are no other parameters or else all other parameters have default arguments

6 A declaration of a constructor for a class X is ill-formed if its first parameter is of type (optionally cv-qualified) X and either there are no other parameters or else all other parameters have default arguments

The purpose of a copy constructor is to define the way you copy an object. So, requiring a copy to be made to call the copy constructor... not so good.
