1 35

Explanation:

* There is a little typo in printf. It should be "/n".

Initially, the value of the first is 1, and the value of the second is 2. Then, do_something (&second, first) is called. The value of the first will still be 1. However, there is a call by reference for second variable. That means the change made by the function do_something will affect the value of the second variable.

When you look at the calculation inside the do_something function, you may see that value of the second will be 35.
