Pointers in swap values

[makan007]

I would like to know how can the swapping function be implemented using pointers, void swap (int*, int*)

//function prototypes
void swap(int& a, int& b);

//function (passing by ref)
void swap(int& a, int& b)
{
  int t = a;
  a = b;
  b = t;
}

Is this correct?

//Using pointers
void swap(int *num1, int *num2) 
{
int tempvar1;


tempvar1 = *num1;
*num1 = *num2;
*num2 = tempvar1;

Yes.
