why i get this?

Question

Frist of all take a look at the following source code
class A {};
int main (){
A a ;
cout <<&a;
/* some address will be appear but if i do it like this one */
A b() ;
cout <<&b;
// i get 1 ! why?

Answer 1

You are getting 1 because you have written "A b();" instead of "A b;". You have declared a function "b()" instead of writing "b".
