Here is a small function definition:
void f(int i, int &k)
{
i = 1;
k = 2;
}
Suppose that a main program has two integer variables x and y, which are given the value 0. Then the main program calls f(x,y); What are the values of x and y after the function f finishes?
- Both x and y are still 0.
- x is now 1, but y is still 0.
- x is still 0, but y is now 2.
- x is now 1, and y is now 2.
