adress value

[vFreeman]

parameter in negative function is an adress But i can send as int
and the program gives correct result why?

 void negative(int &i) ;

int main()
{
	int k = 10 ;
	cout << "positive : " << k << endl;
	int &j = k ;
	cout << "j : " << &j << endl;
	negative(j);
	cout << "negative : " << k << endl;
	return 0 ;
}

void negative(int &i)
{
	i = - i ;
}

OK Compiler does this automatically.

No, it isn't. It's a reference.
