Why is this one showing error?

hi @cbcao263

abc(int x,int y=0)
	{
		cout<<"Inside Cons 2";
	}

remove y=0 this will run

by making this function you make an ambigous statement

as when you call abc obj(3)

which one should call??
as in above function second parameter is default so this may also called or previous one can be called
