I want to discuss this problem can someone understand me this problem?

Question

What is the output of this code?
int x = 50;
int &y = x;
++x;
cout << ++x + y;

Answer 1

x = 50 initial state
y stores the address of x
++x; changes x to 51
and cout << ++x + y; here ++x will increment x again and making it 52 then y will call the x from the address. Which has 52 there as well
So 52 + 52 = 104

Answer 2

int &y = x;

Here we create an int reference, and we initialize it by setting the reference to point to variable <x>. From this moment on, <y> behaves like an alias for <y>, whatever happens to <x> also happens to <y>.
