It should be 10 10.
Both xx and yy are referring to x, but the increment is given only to 'xx' which is why it should be 11 since it is a post increment the result will be displayed as 10 only and the value stored is 11 and coming to yy it is displayed as 10.

Note:
The code print xx and yy, instead of x and y.
x should be 10, and y should be 11.
However, xx and yy are both 11.

It is xx++ not ++xx.
So the first output is 10.
Second output is 11 as xx and yy has the same reference giving yy value to y actually means giving xx value to y but xx has been incremented by 1 to 11.
So the first output is 10.

How can it be posssible, as it is x++ not ++x?
So acc to me output must be 10, 10.

xx++ makes its value 11 and as yy referring to xx, its value also becomes 11.
