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

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>. https://www.differencebetween.com/difference-between-pointer-and-vs-reference/
