Catalina Brandt · Answer 1

b) void xyzfunc (int &myint);

Explanation:

To use the same memory location as the variable in the calling function we have to pass the variable by reference means passing the same address to the function. So to do that we have use & operator which stands for address.

We will do this as following:-

void xyzfunc (int * myint);

Hence the answer is option b.
