Question: Suppose we have a function with the following function signature: void swap ( int , int ) ; and in main we have local variables

Suppose we have a function with the following function signature:
void swap(int, int);
and in main we have local variables x, y, both of type int. Then, because C has pointers, it's possible to call swap(x, y) and swap the values of x and y inside our function and then see these changes in main once we return from swap.
